Tudor Black Bay GMT: A Watch for Life on the Go

The Black Bay GMT blends the advantages of the Black Bay diving watch with the practicality of displaying three time zones at once. Its blue and red 24-hour bezel and in-house caliber make it an affordable alternative to the Rolex GMT-Master II.


A Diving Watch with a GMT Function and Pepsi Bezel

Tudor added the Black Bay GMT to its beloved diving watch collection in 2018. This model is capable of displaying up to three times zones at once. The Swiss manufacturer clearly took inspiration from one of its sister company's most iconic watches, the {man-rolex,Rolex} GMT-Master, when designing this timepiece.

The Black Bay GMT even shares a color scheme with its famous Rolex cousin. Both feature a bidirectional 24-hour bezel in the beloved blue and red "Pepsi" design. The dial is matte black with applied indices and a date display at 3 o'clock. While most of the hour markers are dot indices, there are rectangular bar indices for 6 and 9 o'clock, as well as an inverted triangle at 12. White luminous material fills the hands and indices. The stamped minute track and inscriptions are also white. Only the central 24-hour hand stands out in bright red.

That being said, the Black Bay GMT is anything but a copy of the GMT-Master. It boasts everything that makes the Black Bay collection so popular, including a 41-mm stainless steel case, large crown without a crown guard, and domed sapphire crystal without a magnifying lens. Perhaps the most notable feature that sets this model apart is its square-tipped Snowflake hands. What's more, the Black Bay GMT is water-resistant to 200 m (20 bar, 656 ft), while the GMT-Master is only rated to 100 m (10 bar, 328 ft).

The in-house caliber MT5652 powers the Black Bay GMT. Paired with the bezel, it can display up to three time zones simultaneously. It also has a 70-hour power reserve and comes with chronometer certification from the Official Swiss Chronometer Testing Institute (COSC).

Reasons to Buy a Black Bay GMT

  • Highly popular "Pepsi" design
  • Displays up to three time zones simultaneously
  • COSC-certified in-house caliber MT5652
  • Water-resistant to 200 m (20 bar, 656 ft)

Prices at a Glance: Black Bay GMT

Reference number Price (approx.) Feature(s)
M79830RB-0001 3,900 USD Three-piece stainless steel bracelet with rivets
M79830RB-0002 3,900 USD Brown leather strap with folding safety clasp
M79830RB-0003 3,800 USD Black textile strap with buckle

Tudor Black Bay GMT: Information and Prices

The Black Bay GMT measures 41 mm in diameter. Its stainless steel case is satin brushed on both the top and bottom, while the polished sides add a touch of elegance. The bezel is also made of stainless steel. It features a 24-hour bezel with a red and blue anodized aluminum inlay.

Tudor offers this watch on a stainless steel bracelet under the reference number M79830RB-0001. Like the case, the bracelet links have brushed tops and bottoms and polished sides. The designers decided to mimic the look of the riveted bracelets that were popular in the 1950s and 60s. However, the Black Bay's links actually screw together, so the rivets are purely decorative. Plan to spend between 3,700 and 3,900 USD on one of these timepieces.

If you're not a big fan of metal bracelets, you may prefer the ref. M79830RB-0002. This model comes on a distressed "Terra di Siena" leather bracelet. The red-brown hue lends this watch a particularly rustic look. You can purchase a mint-condition timepiece on Chrono24 for around 3,900 USD. Pre-owned pieces cost slightly less at about 3,400 USD.

Tudor pairs the third version of the Black Bay GMT, the ref. M79830RB-0003, with a black textile strap. A red line runs down the strap's center for an extra sporty touch. Unlike the steel and leather editions, which both use a folding safety clasp, the textile strap comes with a pin buckle. Prices for this model fall between 3,300 USD pre-owned and 3,800 USD new.


About the In-House Caliber MT5652

Tudor developed the caliber MT5652 specifically for the Black Bay GMT. This movement is based on the in-house caliber MT5602, which first appeared in 2015 and has since come to power nearly every three-hand Black Bay watch. It ticks at a frequency of 28,800 alternations per hour (A/h) and has a 70-hour power reserve. It's also resistant to strong magnetic fields thanks to its silicon balance spring. Not even strong jolts can knock this movement out of sync since its balance is held in place by bridges instead of conventional balance cocks. The MT5652 is also a COSC-certified chronometer, meaning it is extremely accurate.

Tudor has put just as much care into the caliber's GMT function. Like its Rolex counterpart, the MT5652 enables the wearer to set local and home time zones separately. For example, to adjust the local time, you simply pull the crown out to its first position to move the hour hand forwards or backwards in one-hour increments without having to completely stop the watch. The movement is even able to account for date changes.
