Rolex introduced the Milgauss watch in 1956 and Omega presented the Railmaster in 1957. While these two models have never been superstars in either brands\u2019 lineup, they continue to be a part of the companies\u2019 current collections and each has its own fan base.

So for a like-for-like comparison, we\u2019ve selected the most recent versions of the Rolex Milgauss ref. 116400 and the Omega Railmaster 220.10.40.20.01.001.\u00a0<\/span><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-36384\" title=\"Rolex Milgauss ref. 116400\" src=\"https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/08\/Rolex-Black-Milgauss-116400-126837.jpg\" alt=\"Rolex Milgauss vs Omega Railmaster\" width=\"300\" height=\"564\" srcset=\"https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/08\/Rolex-Black-Milgauss-116400-126837.jpg 505w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/08\/Rolex-Black-Milgauss-116400-126837-159x300.jpg 159w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/08\/Rolex-Black-Milgauss-116400-126837-202x380.jpg 202w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/p>\n<p><span style=\"font-weight: 400;\">The Rolex Milgauss ref. 116400 made its debut in 2007 and with its arrival, it revived the discontinued Milgauss collection. It sports a 40mm stainless steel case, a smooth steel bezel, and a steel Oyster link bracelet. This particular version includes a time-only black dial, punctuated with plenty of orange details. There are the orange accents adjacent to the lume-filed baton indexes, the orange MILGAUSS name, and of course, the orange lightning bolt seconds hand. This thunderbolt touch harkens back to early Milgauss models, which also featured a similar seconds hands but in a more discreet shade.\u00a0<\/span><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-36385\" title=\"Omega Railmaster ref. 220.10.40.20.01.001\" src=\"https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/08\/Omega-Railmaster-Co-Axial-Master-Chronograph-220.10.40.20.01.001-124629.jpg\" alt=\"Rolex Milgauss vs Omega Railmaster\" width=\"300\" height=\"564\" srcset=\"https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/08\/Omega-Railmaster-Co-Axial-Master-Chronograph-220.10.40.20.01.001-124629.jpg 505w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/08\/Omega-Railmaster-Co-Axial-Master-Chronograph-220.10.40.20.01.001-124629-159x300.jpg 159w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/08\/Omega-Railmaster-Co-Axial-Master-Chronograph-220.10.40.20.01.001-124629-202x380.jpg 202w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/p>\n<p><span style=\"font-weight: 400;\">The Omega Railmaster 220.10.40.20.01.001 was released a decade later at Baselworld 2017 but it is clearly vintage-inspired it its style. Similar to the Milgauss, this Railmaster has a 40mm stainless steel case, steel bezel, steel three-link bracelet, and a time-only dial. The dial however, features a brushed vertical pattern, 3\/6\/9\/12 Arabic numerals, triangular hour markers, and faux-patina Super-LumiNova luminescence (which looks slightly orange) for a vintage look.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Side-by-side, the Rolex Milgauss ref. and the Omega Railmaster are quite similar &#8211; although the first offers a contemporary approach while the latter is going for a retro aesthetic.\u00a0<\/span><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-36390 size-full\" title=\"Rolex Milgauss ref. 116400\" src=\"https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/08\/z127244-x-Rolex-Milgauss-116400V-127244s.jpg\" alt=\"Rolex Milgauss vs Omega Railmaster\" width=\"800\" height=\"800\" srcset=\"https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/08\/z127244-x-Rolex-Milgauss-116400V-127244s.jpg 800w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/08\/z127244-x-Rolex-Milgauss-116400V-127244s-250x250.jpg 250w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/08\/z127244-x-Rolex-Milgauss-116400V-127244s-300x300.jpg 300w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/08\/z127244-x-Rolex-Milgauss-116400V-127244s-768x768.jpg 768w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/08\/z127244-x-Rolex-Milgauss-116400V-127244s-140x140.jpg 140w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/08\/z127244-x-Rolex-Milgauss-116400V-127244s-380x380.jpg 380w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/p>\n<h2><b>Functions and Price: Rolex Milgauss vs Omega Railmaster\u00a0<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">As previously mentioned, both the Milgauss and the Railmaster are time-only models with just three hands on the dial for hours, minutes, and seconds.

Caliber 3131 operates at a frequency of 28,800 beats per hour, has a 48-hour power reserve, and is chronometer-certified. On the other hand, the Omega Railmaster runs on the Co-Axial Master Chronometer Caliber 8806, which is also self-winding but provides a longer power reserve of 55 hours and boasts magnetic resistance up to 15,000 gauss! Lastly, the Caliber 8806 is also chronometer certified, but Omega went a step further by gaining a Swiss Federal Institute of Metrology (METAS) certificate for the movement, which requires even more stringent parameters than COSC certification.\u00a0<\/span><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-36387 size-full\" title=\"Omega Seamaster Railmaster 220.10.40.20.01.001\" src=\"https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/08\/zOmega-Railmaster-Co-Axial-Master-Chronograph-220.10.40.20.01.001-124629-p.jpg\" alt=\"Rolex Milgauss vs Omega Railmaster\" width=\"800\" height=\"800\" srcset=\"https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/08\/zOmega-Railmaster-Co-Axial-Master-Chronograph-220.10.40.20.01.001-124629-p.jpg 800w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/08\/zOmega-Railmaster-Co-Axial-Master-Chronograph-220.10.40.20.01.001-124629-p-250x250.jpg 250w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/08\/zOmega-Railmaster-Co-Axial-Master-Chronograph-220.10.40.20.01.001-124629-p-300x300.jpg 300w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/08\/zOmega-Railmaster-Co-Axial-Master-Chronograph-220.10.40.20.01.001-124629-p-768x768.jpg 768w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/08\/zOmega-Railmaster-Co-Axial-Master-Chronograph-220.10.40.20.01.001-124629-p-140x140.jpg 140w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/08\/zOmega-Railmaster-Co-Axial-Master-Chronograph-220.10.40.20.01.001-124629-p-380x380.jpg 380w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/p>\n<p><span style=\"font-weight: 400;\">While the current black Railmaster is newer, offers greater higher resistance to magnetism, and provides a longer power reserve, it is roughly half the price of the\u00a0 similar looking Milgauss on the secondary market. This is yet another example of the power of the Rolex brand name and the understanding that Rolex watches generally command higher price points, both new and on the secondary market.
