Our take on the Tudor Black Bay 58 Ref. M7939A1A0NU-0001

The Black Bay 58 is Tudor's dive watch sized down to 39mm, and this reference adds a date and a bracelet. It runs the in-house MT5402 automatic with a 65-hour power reserve, a sapphire crystal, 200m water resistance and a black dial with applied indexes and lume. It suits people who want a slim, wearable diver with real dive-watch credentials without paying Rolex money. Against the 41mm Black Bay it wears smaller and thinner, and against the no-date 58 it trades symmetry for a date window.

Questions and answers

How does the Black Bay 58 differ from the regular Black Bay?
The 58 is 39mm and thinner, while the regular Black Bay is 41mm and chunkier. The 58 also has a slimmer bezel and a more vintage-inspired dial.
Does this version have a date?
Yes. This reference adds a date window at 3 o'clock, which the standard no-date Black Bay 58 lacks.
Is 39mm too small for a man's wrist?
No. 39mm is a common dive-watch size that suits most wrists, and many owners prefer it to 41mm for comfort.
Can I swim and dive with it?
Yes. It is rated to 200m with a screw-down crown, so swimming and recreational diving are fine.
How long does it run without winding?
About 65 hours on a full wind, so it keeps running over a weekend off the wrist.
What is in the box?
The watch on its steel bracelet, with Tudor's warranty card and paperwork. Strap options vary by reference.
Where is the Tudor Black Bay 58 Ref. M7939A1A0NU-0001 cheapest?
