Tudor Black Bay 58 GMT

Ref. m7939g1a0nru-0002
GMT

The Tudor Black Bay 58 GMT is widely praised for its functional, proportional, and ergonomic design, wearing identically to the standard Black Bay 58 and feeling substantial without being oversized. Owners are very happy with the 39mm case proportions, noting an improved 12.8mm height. The gilt dial aesthetics and gilt-effect accents are a point of praise for some, while others find them divisive. The Tudor Black Bay 58 GMT features the METAS-certified MT5450-U movement, which is anti-magnetic to 15,000 Gauss and offers a 65-hour power reserve. On balance, owners and reviewers rate the Tudor Black Bay 58 GMT highly for its improved case proportions and gilt dial aesthetics.
