Since then, the Day-Date, better known as the President watch, has grown to become Rolex&#8217;s ultimate symbol of prestige &#8211; a watch that denotes success and affluence.<\/p>\n<p>For over fifty years, the Rolex President was exclusively available with a 36mm case. While there have been 39mm versions of the Day-Date, these were fitted with Pearlmaster bracelets and called Masterpiece Day-Date watches. Therefore, they are not considered true Rolex Presidential watches. 36mm was the classic size for the Day-Date since the very beginning but for some, it was too small for a men&#8217;s watch &#8211; even for a dress timepiece.<\/p>\n<p>Therefore, in 2008, the Swiss watchmaker unveiled a noticeably larger Rolex President model fitted with a 41mm case named the <a href=\"https:\/\/www.bobswatches.com\/rolex-day-date-ii-1.html\" title=\"Rolex Day-Date II\">Rolex Day-Date II<\/a>. Then, seven short years later, Rolex replaced the Day-Date II with the slightly smaller Day-Date 40 model. Given their similar dimensions and styles, there can be some confusion as to how these two larger Day-Date watches differ from each other. So, let&#8217;s explore the differences and similarities between the Day-Date II and the Day-Date 40 to determine which Rolex President is the right fit for you.<\/p>\n<h2>Rolex Day-Date II vs. Rolex Day-Date 40<\/h2>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-45801 size-full\" title=\"Rolex Day-Date 40 ref. 228238\" src=\"https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2017\/10\/Screen-Shot-2021-01-04-at-12.22.07-PM.jpg\" alt=\"Rolex Day-Date II vs Day-Date 40 Reference 228238\" width=\"1180\" height=\"882\" srcset=\"https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2017\/10\/Screen-Shot-2021-01-04-at-12.22.07-PM.jpg 1180w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2017\/10\/Screen-Shot-2021-01-04-at-12.22.07-PM-300x224.jpg 300w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2017\/10\/Screen-Shot-2021-01-04-at-12.22.07-PM-768x574.jpg 768w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2017\/10\/Screen-Shot-2021-01-04-at-12.22.07-PM-1024x765.jpg 1024w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2017\/10\/Screen-Shot-2021-01-04-at-12.22.07-PM-508x380.jpg 508w\" sizes=\"(max-width: 1180px) 100vw, 1180px\" \/><\/p>\n<h3>Rolex Day-Date II<\/h3>\n<p style=\"padding-left: 30px;\"><strong>Production Period:<\/strong> 2008 \u2013 2015<\/p>\n<p style=\"padding-left: 30px;\"><strong>Case size:<\/strong> 41mm<\/p>\n<p style=\"padding-left: 30px;\"><strong>Materials:<\/strong> Yellow gold, white gold, Everose gold, or platinum<\/p>\n<p style=\"padding-left: 30px;\"><strong>Bezel:<\/strong> Gold fluted, smooth platinum, or diamond-set<\/p>\n<p style=\"padding-left: 30px;\"><strong>Bracelet:<\/strong> President<\/p>\n<p style=\"padding-left: 30px;\"><strong>Water-Resistance:<\/strong> 100 meters \/ 330 feet<\/p>\n<p style=\"padding-left: 30px;\"><strong>Movement:<\/strong> Caliber 3156<\/p>\n<h3>Rolex Day-Date 40<\/h3>\n<p style=\"padding-left: 30px;\"><strong>Production Period:<\/strong> 2015 &#8211; Present<\/p>\n<p style=\"padding-left: 30px;\"><strong>Case size:<\/strong> 40mm<\/p>\n<p style=\"padding-left: 30px;\"><strong>Materials:<\/strong> Yellow gold, white gold, Everose gold, or platinum<\/p>\n<p style=\"padding-left: 30px;\"><strong>Bezel:<\/strong> Gold fluted, smooth platinum, or diamond-set<\/p>\n<p style=\"padding-left: 30px;\"><strong>Bracelet:<\/strong> President<\/p>\n<p style=\"padding-left: 30px;\"><strong>Water-Resistance:<\/strong> 100 meters \/ 330 feet<\/p>\n<p style=\"padding-left: 30px;\"><strong>Movement:<\/strong> Caliber 3255<\/p>\n<p style=\"padding-left: 30px;\"><strong><a href=\"https:\/\/www.bobswatches.com\/rolex-blog\/buying-guides\/rolex-day-date-ultimate-buying-guide.html\" title=\"Ultimate Buying Guide on the Rolex Day-Date Day Date\">Click here for our Ultimate Buying Guide on the Rolex Day-Date.<\/a><\/strong><\/p>\n<p><a href=\"https:\/\/www.bobswatches.com\/rolex-day-date-ii-1.html\" title=\"Rolex Day-Date II\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-45053 size-full\" title=\"Shop Rolex Day-Date II Watches\" src=\"https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2017\/11\/shop-the-collection1.jpg\" alt=\"Rolex Day-Date II\" width=\"436\" height=\"46\" srcset=\"https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2017\/11\/shop-the-collection1.jpg 436w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2017\/11\/shop-the-collection1-300x32.jpg 300w\" sizes=\"(max-width: 436px) 100vw, 436px\" \/><\/a><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-45797 size-full\" title=\"Rolex Day-Date II ref. 218235 - Everose Gold\" src=\"https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2017\/10\/Rolex_DayDate_218235_5D3_0872_Edit-1.jpg\" alt=\"Rolex Day-Date II vs Day-Date 40 Reference 218235 Everose Gold\" width=\"1180\" height=\"787\" srcset=\"https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2017\/10\/Rolex_DayDate_218235_5D3_0872_Edit-1.jpg 1180w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2017\/10\/Rolex_DayDate_218235_5D3_0872_Edit-1-300x200.jpg 300w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2017\/10\/Rolex_DayDate_218235_5D3_0872_Edit-1-768x512.jpg 768w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2017\/10\/Rolex_DayDate_218235_5D3_0872_Edit-1-1024x683.jpg 1024w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2017\/10\/Rolex_DayDate_218235_5D3_0872_Edit-1-570x380.jpg 570w\" sizes=\"(max-width: 1180px) 100vw, 1180px\" \/><\/p>\n<h2>Size Differences: Day-Date II Vs Day-Date 40<\/h2>\n<p>The Oyster case of the Rolex Day-Date II measures 41mm, while (as its name suggests) the Day-Date 40 measures 40mm. Although on the outset the 1mm difference seems trivial, wearing the watch is a different story. Due to its thicker lugs, chunkier build, and wider bezel, the Rolex Day-Date II wears larger and offers a bolder wrist presence than the 1mm variance suggests.<\/p>\n<p>Conversely, not only did Rolex trim 1mm from the case size of the Day-Date 40, but its overall style is more elegant thanks to a thinner profile, thinner bezel, and slimmer lugs. It may be hard to tell with a quick glance but if you hold the two models side-by-side, the differences become quite apparent.<\/p>\n<p>In short, the size variations and silhouette redesign mean that the Day-Date II is regarded as the slightly sportier choice, while the Day-Date 40 is more aligned with the classic 36mm Day-Date style but in a larger format.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-45792 size-full\" title=\"Rolex Day-Date II vs. Rolex Day-Date 40 - Platinum\" src=\"https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2017\/10\/Screen-Shot-2021-01-04-at-12.08.40-PM.jpg\" alt=\"Rolex Day-Date II vs Day-Date 40 - Platinum Ice Blue\" width=\"1180\" height=\"943\" srcset=\"https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2017\/10\/Screen-Shot-2021-01-04-at-12.08.40-PM.jpg 1180w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2017\/10\/Screen-Shot-2021-01-04-at-12.08.40-PM-300x240.jpg 300w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2017\/10\/Screen-Shot-2021-01-04-at-12.08.40-PM-768x614.jpg 768w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2017\/10\/Screen-Shot-2021-01-04-at-12.08.40-PM-1024x818.jpg 1024w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2017\/10\/Screen-Shot-2021-01-04-at-12.08.40-PM-476x380.jpg 476w\" sizes=\"(max-width: 1180px) 100vw, 1180px\" \/><\/p>\n<h2>Material, Bezel, and Dial Variations: Day-Date II Vs Day-Date 40<\/h2>\n<p>One of the defining characteristics of all Rolex Day-Date watches, regardless of size or era, is their precious metal construction. Unlike its other models that offer steel or two-tone steel\/gold variations, Rolex has only ever made the Day-Date in solid 18k gold or platinum. Nothing but the best for the Presidential watch and of course, this choice of material makes the Day-Date one of the priciest Rolex watches to own.<\/p>\n<p>As always, both the Rolex Day-Date II and the Day-Date 40 collections offer iterations in yellow gold, white gold, Everose gold (Rolex\u2019s proprietary rose gold alloy), and platinum. The gold variations come fitted with the classic fluted bezel while the platinum versions sport smooth bezels. Naturally, certain Rolex Day-Date II and Day-Date 40 watches also have the option of factory diamond-set bezels, including both round-cut and baguette-cut.<\/p>\n<p>In true Rolex fashion, there are plenty of dial styles to choose from within both the Day-Date II and Day-Date 40, from various hour marker styles like Arabic numerals, Roman numerals, and diamonds to numerous colors like champagne, black, and silver. As is tradition with platinum Rolex watches, the platinum Day-Date 40 and Day-Date II models can also come with ice-blue dials. Furthermore, when Rolex introduced the Day-Date 40 in 2015, the company debuted a new laser etching process to create dial patterns including stripes, crisscross, and quadrant motifs.<\/p>\n<p>Following in the footsteps of the classic Day-Date 36, the larger Day-Date watches feature a day window arching above 12 o\u2019clock, which is available in 26 different languages. Also, the date window at 3 o&#8217;clock is magnified by a Cyclops lens protruding from the surface of the sapphire crystal above it.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-45730 size-full\" title=\"Rolex Day-Date 40 ref. 228238 - Yellow Gold\" src=\"https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2021\/01\/Screen-Shot-2020-12-30-at-1.24.23-PM.jpg\" alt=\"Rolex Day-Date II vs Day-Date 40 Reference 228238 Yellow Gold\" width=\"1180\" height=\"886\" srcset=\"https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2021\/01\/Screen-Shot-2020-12-30-at-1.24.23-PM.jpg 1180w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2021\/01\/Screen-Shot-2020-12-30-at-1.24.23-PM-300x225.jpg 300w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2021\/01\/Screen-Shot-2020-12-30-at-1.24.23-PM-768x577.jpg 768w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2021\/01\/Screen-Shot-2020-12-30-at-1.24.23-PM-1024x769.jpg 1024w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2021\/01\/Screen-Shot-2020-12-30-at-1.24.23-PM-506x380.jpg 506w\" sizes=\"(max-width: 1180px) 100vw, 1180px\" \/><\/p>\n<h2>Day-Date II and Day-Date 40 References<\/h2>\n<p>One way to distinguish between the Rolex Day-Date II and the Day-Date 40 is to look at the reference numbers.

Alternatively, the Rolex Day-Date 40 is a current-production model, and it can be purchased either at a retail level or from the secondary market.<\/p>\n<p>The starting price for a brand-new Rolex Day-Date 40 at retail is $36,550 for the yellow gold ref. 228238. Prices quickly go up from there for diamond embellishments on the bezel or dial and for other material options &#8211; platinum, white gold, and Everose gold all cost more than traditional 18k yellow gold.<\/p>\n<p>While not too long ago there used to be about a $10,000 difference between the Rolex Day-Date II and Day-Date 40, the value of the Day-Date II has increased quite dramatically where price points for both models are now quite similar on the secondary market, and both are currently trading hands for values above their original retail prices. For instance, pre-owned Rolex Day-Date II ref. 218238 and Day-Date 40 ref. 228238 watches start out at around the $40,000 mark.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-45800 size-full\" title=\"Rolex Day-Date 40 ref. 228239 - Diamond Dial\" src=\"https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2017\/10\/Rolex_DayDate_228239_5D3_1942_Edit-4-1.jpg\" alt=\"Rolex Day-Date II vs Day-Date 40 Reference 228239 Diamond Dial\" width=\"1180\" height=\"787\" srcset=\"https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2017\/10\/Rolex_DayDate_228239_5D3_1942_Edit-4-1.jpg 1180w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2017\/10\/Rolex_DayDate_228239_5D3_1942_Edit-4-1-300x200.jpg 300w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2017\/10\/Rolex_DayDate_228239_5D3_1942_Edit-4-1-768x512.jpg 768w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2017\/10\/Rolex_DayDate_228239_5D3_1942_Edit-4-1-1024x683.jpg 1024w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2017\/10\/Rolex_DayDate_228239_5D3_1942_Edit-4-1-570x380.jpg 570w\" sizes=\"(max-width: 1180px) 100vw, 1180px\" \/><\/p>\n<h2>Which Rolex President Will It Be?<\/h2>\n<p>To sum up the similarities and differences between the Rolex Day-Date II and the Rolex Day-Date 40, here\u2019s a quick table of their specifications.<\/p>\n<table style=\"height: 234px;\" width=\"100%\" border=\"1\" hspace=\"5\" vspace=\"5\" padding: 15px;>\n<tbody>\n<tr bgcolor=\"lightblue\">\n<td><strong>&nbsp; Model<\/strong><\/td>\n<td><strong>&nbsp; Rolex Day-Date II<\/strong><\/td>\n<td><strong>&nbsp; Rolex Day-Date 40<\/strong><\/td>\n<\/tr>\n<tr>\n<td><strong>&nbsp; Production Years<\/strong><\/td>\n<td>&nbsp; 2008 \u2013 2015<\/td>\n<td>&nbsp; 2015 \u2013 Present<\/td>\n<\/tr>\n<tr>\n<td><strong>&nbsp; Case Size<\/strong><\/td>\n<td>&nbsp; 41mm<\/td>\n<td>&nbsp; 40mm<\/td>\n<\/tr>\n<tr>\n<td><strong>&nbsp; Material Options<\/strong><\/td>\n<td>&nbsp; Yellow gold, white gold, Everose gold, platinum<\/td>\n<td>&nbsp; Yellow gold, white gold, Everose gold, platinum<\/td>\n<\/tr>\n<tr>\n<td><strong>&nbsp; Bezel Options<\/strong><\/td>\n<td>&nbsp; Gold fluted, smooth platinum, diamond-set<\/td>\n<td>&nbsp; Gold fluted, smooth platinum, diamond-set<\/td>\n<\/tr>\n<tr>\n<td><strong>&nbsp; Bracelet<\/strong><\/td>\n<td>&nbsp; President; platinum version with ceramic inserts<\/td>\n<td>&nbsp; President; all versions with ceramic inserts<\/td>\n<\/tr>\n<tr>\n<td><strong>&nbsp; Movement<\/strong><\/td>\n<td>&nbsp; Caliber 3156 (48-hour power reserve)<\/td>\n<td>&nbsp; Caliber 3255 (70-hour power reserve)<\/td>\n<\/tr>\n<tr>\n<td><strong>&nbsp; Water-Resistance<\/strong><\/td>\n<td>&nbsp; 100 meters \/ 330 feet<\/td>\n<td>&nbsp; 100 meters \/ 330 feet<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Both models are spectacular larger versions of the quintessential Rolex status-symbol watch and both offer a timeless and classic design that has been in-style since it first made an appearance in 1956.

For some, this was too small for a men\u2019s watch, even for a dress timepiece. So in 2008, the Swiss watchmaker unveiled a much larger Rolex President with the Day-Date II. Then, seven short years later, Rolex introduced yet another version of the Presidential watch with the Day-Date 40, which in fact replaced the President II. Today we explore the differences and similarities between the Day-Date II and the Day-Date 40 so you can determine which Rolex President is the right fit for you. <\/p>\n","protected":false},"author":2,"featured_media":45802,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"ep_exclude_from_search":false,"footnotes":""},"categories":[2171],"tags":[1913,1912],"ppma_author":[2286],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v23.0 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Rolex President Showdown: Day-Date II vs Day-Date 40 - Bob&#039;s Watches<\/title>\n<meta name=\"description\" content=\"What are the main differences between the two larger Rolex President watches?
