Black Bay Heritage, Reimagined with Diamonds
The TUDOR Black Bay One 31 S&G M79613-0005 brings an elegant, jewelry-inspired character to one of TUDOR's most recognizable watch families. Its beautifully proportioned 31mm stainless steel case is framed by a solid yellow gold bezel set with brilliant diamonds, while a deep black dial features diamond hour markers for an additional touch of brilliance.
A five-link steel and yellow gold bracelet completes the design, balancing the warmth of gold with the versatility of stainless steel. Beneath its refined exterior, TUDOR's Manufacture Calibre MT5201 provides COSC-certified mechanical performance and approximately 50 hours of power reserve.
The result is a watch that pairs the heritage and engineering of TUDOR with the elegance of fine jewelry.
Diamonds Meet TUDOR Design
Diamonds transform the character of the M79613-0005 without overwhelming its clean design.
The fixed bezel is crafted in solid yellow gold and set with diamonds, creating a brilliant frame around the black dial. Additional diamond hour markers bring that sparkle onto the dial itself, where their brightness contrasts beautifully against the dark background.
Rather than separating watchmaking and jewelry, this Black Bay brings the two together—mechanical performance on the inside and precious materials on the outside.
Steel & Gold
TUDOR's S&G — Steel & Gold — construction gives the watch warmth while maintaining the versatility needed for everyday wear.
The five-link bracelet combines stainless steel with yellow gold details, complementing the solid yellow gold diamond-set bezel and gold-accented winding crown.
The combination is especially effective against the black dial. Steel keeps the watch contemporary and wearable, while yellow gold and diamonds give it the presence of a fine jewelry piece.
Manufacture Calibre MT5201
Inside the Black Bay One 31 S&G is TUDOR's Manufacture Calibre MT5201, a self-winding mechanical movement with a bidirectional rotor system.
Certified as a chronometer by the COSC, the MT5201 is adjusted by TUDOR to deliver precise everyday performance and provides approximately 50 hours of power reserve.
It's an important part of what makes this watch compelling: beneath its diamond-set exterior is a manufacture mechanical movement built to the same performance-minded philosophy found throughout TUDOR's collection.
Designed for Everyday Elegance
At just 31mm in diameter and 9.5mm thick, the M79613-0005 offers beautifully compact proportions and a refined profile on the wrist.
The flat sapphire crystal keeps the design clean, while the screw-down crown and 100 meters / 330 feet of water resistance provide practical durability for everyday wear.
TUDOR's five-link bracelet is also equipped with the T-fit rapid-adjustment clasp, allowing the fit to be fine-tuned quickly without tools.
It's a thoughtful combination of elegance, comfort, and genuine everyday usability.
The Skeie's Perspective
At Skeie's Jewelers, we think this Black Bay demonstrates just how versatile TUDOR's design language can be. The familiar Black Bay DNA is still there, but the 31mm proportions, diamond-set bezel, diamond hour markers, and yellow gold details give this reference an entirely different personality from the collection's traditional dive watches.
What we especially appreciate is that the diamonds don't feel like an afterthought. The diamond bezel and markers work together with the black dial to create striking contrast, while the five-link bracelet gives the watch a softer, more refined presence on the wrist.
It's elegant enough to wear as jewelry, yet inside is a genuine TUDOR manufacture movement with chronometer-certified performance. That combination makes the M79613-0005 much more than simply a beautiful diamond watch.
