A Professional GMT with Striking New Contrast
The TUDOR Black Bay Pro M79470-0004 combines true GMT functionality with the rugged, purpose-built character of TUDOR's professional watches. Its 39mm stainless steel case is paired with a distinctive opaline dial, creating exceptional contrast against the black-outlined hour markers and hands. The signature yellow 24-hour "Snowflake" hand adds a bold finishing touch while displaying reference time against the fixed 24-hour steel bezel.
Inside is TUDOR's Manufacture Calibre MT5652, a COSC-certified automatic movement developed with an integrated GMT architecture and approximately 70 hours of power reserve. Compact, capable, and unmistakably TUDOR, the Black Bay Pro is built for travelers and collectors who want genuine functionality without an oversized case.
Built for Two Time Zones
The Black Bay Pro is designed around a practical GMT complication. The yellow 24-hour Snowflake hand completes one rotation every 24 hours and displays reference time against the fixed graduated bezel.
Local time is controlled independently through the jumping hour hand, which can be moved forward or backward without disturbing the minutes, seconds, or reference time. The date is linked to local time and adjusts accordingly when crossing midnight—an especially useful feature for frequent travelers.
Manufacture Calibre MT5652
Powering the Black Bay Pro is the TUDOR Manufacture Calibre MT5652, a self-winding mechanical movement with an integrated GMT function.
COSC-certified for chronometer performance, the MT5652 delivers approximately 70 hours of power reserve. That means the watch can be taken off Friday evening and still be running when you return to it Monday morning.
Designed for Everyday Exploration
The Black Bay Pro balances professional capability with proportions that work exceptionally well for daily wear. Its 39mm stainless steel case is water resistant to 200 meters, while the domed sapphire crystal and satin-brushed 24-hour bezel reinforce its tool-watch character.
The riveted stainless steel bracelet is equipped with TUDOR's T-fit rapid-adjustment clasp, allowing the wearer to make quick fit adjustments without tools.
The Skeie's Perspective
At Skeie's Jewelers, we think the opaline dial completely changes the personality of the Black Bay Pro. The original black-dial version has the character of a traditional tool watch, while this version feels brighter, more contemporary, and immediately more legible.
What really makes it work is the contrast. The black surrounds on the hands and markers give the opaline dial definition, while the yellow GMT hand provides just enough color to make the watch distinctive. Add the wearable 39mm case, T-fit bracelet, and true traveler's GMT movement, and this becomes one of the most versatile professional watches in TUDOR's collection.
