What is a Rolex Tridor?

The Rolex term “Tridor” refers to the pairing of three different precious metals, specifically 18k rose, yellow, and white gold. Each metal is fused together, creating perfect, contrasting stripes of different colors of gold that run through the entire length of the bracelet.

The outer links are presented in 18k white gold to match the case, which is usually surrounded by a fluted bezel in yellow gold. The striped center links create intrigue and dimension and reflect 1980s jewelry fashion. Today, the Rolex Tridor is a prized collector’s item among horology enthusiasts for its exclusive retro design.

A President To Remember: Tridor Features

Aside from being the watch of a President, the ref. 18239 features automatic winding technology and a 31-jewel movement. The Rolex President was known for its chronometer-certified precision and, with a waterproof case resistant to a depth of 100 meters, was also known for its durability. The timepiece is topped with a scratch-resistant sapphire crystal with a Cyclops lens that magnifies the date for easier at-a-glance reading.

When the Rolex Day-Date hit the market in the 1950s, it was the first wristwatch to feature both the date and the day of the week spelled out in full on the dial. The date mechanism was already an established mechanism, first appearing on the Datejust a decade prior in 1945. It is ever-present at the 3-hour marker beneath the Cyclops magnification lens. What makes the Day-Date so special is the second display at 12 o’clock, presenting the day spelled out in full, not abbreviated. An innovation of its time, the extra window has since become one of the Rolex Day-Date’s most distinguishing features.

To make the ref. 18239 even more appealing, Rolex used the finest 18k white gold to construct the case and bracelet. The Tridor versions of the watch feature a yellow gold fluted bezel, while the standard version is completely finished in 18k white gold. The President bracelet is exclusive to the Day-Date collection, except for a handful of midsize and Lady-Datejust models. It features semi-circular links that hug the wrist nicely and a concealed Crownclasp that is virtually hidden from the rest of the links, aside from the tell-tale Rolex coronet.

The Movement: Rolex Caliber 3155

Powering the Rolex Tridor 18239 is the Caliber 3155 movement, which boasts self-winding technology. This means that the movement powers itself from the motion of the wearer’s wrist. If worn regularly, there is no need to wind ref. 18239 or set the time or dual calendar apertures. With that said, the movement boasts a 48-hour power reserve. You can put this watch down for a night or two, and it should still read true when you put it back on again.

The Rolex Caliber 3155 also boasts a Double Quickset function, a feature that allows the wearer to adjust either the day or date mechanism with a quick twist of the crown instead of winding it a full 24-hours to advance them day-by-day. Lastly, the Cal. 3155 is chronometer rated, meaning that it has met Rolex’s strict standards for precision and excellence.
