Tudor Black Bay GMT vs. Rolex GMT-Master 2

Since the mid-1950s, Rolex has been building its famous aviation watch GMT-Master, whose current version GMT-Master 2 came out around the year 1982. Developed as a professional instrument for pilots to check different time zones, stainless steel has always been the preferred material of the GMT Master, which has become one of the Rolex bestsellers over the decades. Of course, various precious metal variants also came on the market, but the outstanding feature of the watch from the very beginning was its two-color rotating bezel. Whether the blue-black “Batman” bezel, or the traditional red-blue “Pepsi” version, the fan bases of the different models are large and so the presentation of the new stainless steel version with the red-blue bezel was met with great enthusiasm at the Baselworld watch fair in 2018.

The combination with the Jubilee band was somewhat surprising, otherwise the new model was as had been expected.

But that was not all! If the new GMT-Master 2 “Pepsi” had been predicted by many, Rolex now surprised with a comprehensive “GMT revamp”. More than 60 years after the model was introduced, it has now also been included in the product range of the small sister company Tudor, where it is now enriching the successful Black Bay line.

That Tudor takes over successful models from Rolex is neither new nor surprising. It is easy to see, for example, where the inspiration for Tudor’s popular diver’s watches or the Chronograph came from. So, what would be more logical …? And yet, the industry and the fan base are in turmoil! Can you even do that, just give such an icon a “light” version? Does a GMT not have to be a Rolex GMT-Master … and anyway: what does the Black Bay GMT actually offer the fan of good timekeepers?

The Black Bay GMT is also available with a textile or leather strap

Keep in mind, money is money: its price does not necessarily speak against it, at 3,680 euros with the stainless steel bracelet. This makes it almost unfair to mention that the most affordable variant of its Rolex model is 7,750 euros.

Even though the Tudor Black Bay GMT does not exude the stunning value of its role model, for example regarding the latter’s highly modern Cerachrom ceramic bezel,… it still appears very carefree and joyful. And this impression continues even when put into practice! For example, the Tudor, whose 41 mm diameter housing is 1 mm larger than that of the GMT-Master 2, offers twice the waterproofness, to a depth of 200 meters. Equipped with the modern Caliber MT5652, manufactured by Tudor itself, the performance features of the Black Bay GMT are at the highest level, such as the power reserve of about 70h.

With the Caliber MT5652, which was specially developed for the new watch, the GMT function has arrived at Tudor.

It almost seems as if they had put themselves in a spot, because not all models of the parent company can keep up. For example, the GMT-Master 2 with the black bezel pictured above, still uses the Rolex 3186 Caliber, with a power reserve of “only” 48h. Of course, this is undoubtedly an absolute top class mechanism. Which however will be slowly but surely discontinued, seeing as they have just introduced its successor with the new models, the Caliber 3285, which in terms of performance will again be unrivaled.
