⌚⌚ HOTTudor Black Bay Fifty-Eight "Navy Blue"
39mm heritage diver with in-house MT5402 movement.
Our take on the Tudor Black Bay Fifty-Eight "Navy Blue"
The Black Bay Fifty-Eight is the watch that fixed the one complaint people had about the Black Bay line: size. At 39mm with a 11.9mm thickness, it wears like a vintage Submariner, and the navy blue version added a colour Tudor had reserved for its own history rather than borrowing from Rolex.

Tudor Black Bay Fifty-Eight "Navy Blue" — frequently asked questions
Is the BB58 too small at 39mm?
For most wrists it is the sweet spot. The 41mm Black Bay is the alternative if you want more presence.
Does the Tudor BB58 use a Rolex movement?
No. The MT5402 is Tudor's own in-house calibre, though Tudor and Rolex share quality standards.
