Originally released in 1988, the 16233 Datejust is a 36mm yellow Rolesor version of Rolex’s iconic calendar-display watch. It characterizes stainless steel and 18k gold construction with Rolex’s signature fluted bezel. The 16233 Datejust could be mistaken for a more refined formal replica watch; however, with its 100-meter water resistance, scratch-resistant sapphire crystal, and the proven reliability of its in-house caliber 3135, the Datejust 16233 is an elegant all-day wear watch. 
At 36mm in diameter, the Reference 16233 is a highly versatile package that looks the same on most wrists, regardless of size or gender. What’s more, the Ref. 16233 Datejust predates the advent of Rolex’s “super case” with its thicker lugs, so this version of the Datejust retains the classic proportions that have served as the backbone of the replica Rolex catalog for a few years.
Given the modern prices of many stainless steel models, two-tone Rolex watches are becoming an increasingly attractive value proposition, with slightly older models like the Ref. 16233 Datejust representing some of the best buys in the world of luxury replica watches.
However, it doesn’t take an eagle eye to spot the most obvious difference between the old and the new – the number of subdials. the Co-Axial 9300 allows for a fairly radical redesign of the chronograph. The small second’s indicator is still located at nine o’clock; however, the 12-hour and 60-minute counters have been combined into a single unit and placed at three o’clock. Reducing this historic three-hand layout by one leaves plenty of room – and even adds a date window at 6 o’clock. In addition, the subdial is much larger than before, greatly improving readability and providing an almost perfect balance.
The same goes for the hands, which owe more to the second generation of the speedy than to the first, featuring Alpha-style main hour and minute hands. Nevertheless, if you look closely, the classic Broad Arrow is still there; it now appears as the hour hand of a small chronograph.
Aesthetics aside, it’s the movement that demands the most attention. the 9300 calibers, which debuted in 2011, can be seen through the rounded sapphire back, which makes the Speedmaster ’57 much taller than you might expect. Unlike the chronograph movement it replaces, the Cal. 3313, the Cal. 9300 is designed specifically around the coaxial escapement, rather than as an add-on accessory. However, it gives a rock-solid internal movement and a typical Rolex look at a still relatively affordable price. Rolex’s catalog is full of two-tone watches, but the reference 16233 Datejust is probably the best value available.
