Tudor Black Bay GMT "Coke" Original Box & Papers AMAZING CONDITION

Tudor Black Bay 58 GMT "Coke" Original Box and Papers!


The Black Bay 58 GMT is the watch Tudor fans spent six years begging for — and it was worth every Reddit thread, every forum post, and every passive-aggressive comment under a Watches & Wonders livestream. Tudor already had a GMT in the lineup — the 41mm Black Bay GMT launched in 2018 — but at 14.6mm thick it wore like a hockey puck with snowflake hands. The Black Bay 58 GMT finally marries the compact, universally wearable 39mm case of the BB58 to a proper integrated GMT complication, and does it with one of the most impressive movements at this price point in the industry. The Manufacture Caliber MT5450-U is produced by Kenissi — Tudor's movement-making joint venture with Chanel — and built on the MT5400 architecture that's become the backbone of the modern Black Bay family. This isn't a GMT-via-bolt-on-module; the dual-timezone function is integrated directly into the movement's architecture, which means a jumping local-time hour hand that can be set independently, a 24-hour GMT hand for the reference timezone, and an instantaneous date that stays synchronized with the jumping hour — the exact "flyer" GMT configuration that collectors obsess over. A non-magnetic silicon balance spring, free-sprung variable-inertia balance, and traversing bridge with two-point anchoring handle the regulation, beating at 28,800 vph with a 65-hour power reserve. And the certification story is where this watch quietly flexes hardest: it carries both COSC chronometer certification and METAS Master Chronometer certification, meaning the fully assembled watch has been tested to 0/+5 seconds per day and rated anti-magnetic to 15,000 gauss. Tudor under-promises -2/+4 on their own watches; METAS holds them to an even tighter 5-second window. For a watch at this price, that is a staggering level of third-party validation.


What makes this particular reference the one that broke the internet is the bezel. Black and burgundy — the "Coke" colorway — on a bidirectional 24-hour rotating ring in anodized aluminum with gilt markings, and it immediately evokes the bakelite-bezel vintage Rolex GMT-Masters that trade for six figures on a slow day. Tudor leans into that golden-age-of-air-travel aesthetic hard: the domed matte black dial carries gilt applied indices — circular pips, rectangular bars, and an inverted triangle at 12 — with matching gilt snowflake hands for the hours and GMT function, a lollipop seconds hand, and warm-toned SuperLuminova fills. The overall effect is a watch that looks like it's already been aged by 50 years of stories, even straight out of the box. At 39mm across, 47.8mm lug-to-lug, and 12.8mm thick, it's dramatically more wearable than any previous Tudor GMT — nearly 2mm thinner than the 41mm version — and the domed sapphire crystal helps the profile melt into the wrist rather than sitting on top of it. The redesigned screw-down crown sits flush with the case, hiding the tube in a nod to Tudor's first dive watches, and the three-link riveted steel bracelet with T-fit quick-adjust clasp (no tools required) rounds out a package that feels purpose-built for people who actually travel with their watch on. This is the compact GMT that everybody wanted from Tudor, in the colorway everybody wanted from Rolex.
