See price at Bob's Watches

The pre-owned Tudor Black Bay 58 GMT with a black dial is currently listed at $4,695 and comes with box and papers, while the iconic Rolex GMT-Master II “Pepsi” (ref 126710BLRO) sits at $25,995, a price gap of roughly 5.5 times. At that spread, the Tudor’s premium over the base Black Bay 58 (which sells for $4,195) is only about $500, yet it delivers an in-house MT5652 GMT movement, a 39 mm case that many find more wearable, and the same independently-adjustable hour hand that Rolex offers. In plain terms: if you want a genuine GMT complication without the Rolex price tag, the Tudor Black Bay 58 GMT is the most cost-effective entry point on the pre-owned market today.

How We Chose These Watches

Our selection process was built around three objective criteria: live market price, condition with original box and papers, and the presence of an in-house GMT movement. We verified every price on the product pages of Bob’s Watches on 5 September 2026, confirming that each listing met the “Pre-Owned Excellent” condition standard and included box and papers. The Tudor pieces all share the MT5652 movement, while the Rolex model features Rolex’s own GMT calibre. By limiting ourselves to a single, reputable dealer we ensured price consistency and avoided speculative listings. Sources for each watch are cited in the individual product sections below.

Pre-Owned Stainless Steel Tudor Black Bay 58 GMT Black Dial

Price: $4,695 - live as of 5 Sept 2026 Bob’s Watches
Reference: M7939G1A0NRU-0001
Case Size: 39 mm
Condition: Pre-Owned Excellent (very slight signs of wear)
Box & Papers: Included

Who It’s For

This watch is the clearest entry point for buyers who want a true in-house GMT complication without paying Rolex-level prices. The 39 mm case sits a millimetre smaller than most sport-style GMT watches, making it a comfortable daily driver for both smaller and larger wrists. The inclusion of box and papers at this price point adds confidence for collectors who value provenance.

What We Would Change

The only notable limitation is the case size; some buyers accustomed to 40 mm+ GMT models may find the 39 mm case feels a touch undersized. Additionally, the listing does not confirm which bracelet or strap is included, so buyers should verify strap options before purchase.

Used Black & Burgundy Bezel Tudor Black Bay 58 GMT Steel

Price: $4,695 - live as of 5 Sept 2026 Bob’s Watches
Reference: M7939G1A0NRU-0001
Case Size: 39 mm
Condition: Pre-Owned Excellent (very slight signs of wear)
Box & Papers: Included

Who It’s For

If you prefer a little visual flair, the two-tone black-and-burgundy bezel offers a distinct look while retaining the same MT5652 GMT movement and 39 mm case as the black-dial version. It’s ideal for buyers who want a subtle splash of colour without stepping outside the Black Bay family aesthetic.

What We Would Change

Because this SKU is a single used piece rather than a stocked model, the price can shift between visits. Prospective buyers should monitor the listing closely and be prepared for minor price fluctuations.

Used Tudor Black Bay Fifty-Eight Brown Dial Ref 79012

Price: $5,195 - live as of 5 Sept 2026 Bob’s Watches
Reference: 79012
Case Size: 39 mm
Condition: Pre-Owned Excellent
Box & Papers: Included

Who It’s For

Collectors who prize dial rarity will find the brown dial with bronze-tone bezel compelling. Despite lacking a GMT function, this piece commands a higher price than the GMT-equipped models, illustrating how colour scarcity can outweigh complications in the Black Bay 58 line.

What We Would Change

The absence of a GMT complication means this watch cannot serve travelers or dual-time-zone enthusiasts. Buyers prioritising functionality over dial novelty should look elsewhere.

Pre-Owned Stainless Steel Tudor Black Bay 58 Blue Dial Ref 79030B

Price: $4,195 - live as of 5 Sept 2026 Bob’s Watches
Reference: 79030B
Case Size: 39 mm
Condition: Pre-Owned Excellent (very slight signs of wear)
Box & Papers: Included

Who It’s For

This is the most affordable Black Bay 58 in the current pre-owned market, establishing the family’s price floor. It shares the same 39 mm case and in-house automatic movement family as the GMT models, making it a solid choice for buyers who love the Black Bay silhouette but do not need a second time-zone display.

What We Would Change

The lack of a GMT function means the watch is priced roughly $500 lower than the GMT-equipped Black Bay 58, confirming that the GMT complication adds a modest premium rather than a dramatic cost jump.

Pre-Owned Rolex GMT-Master II Pepsi Ref 126710BLRO Oyster Bracelet

Price: $25,995 - live as of 5 Sept 2026 Bob’s Watches
Reference: 126710BLRO
Case Size: 40 mm
Condition: Pre-Owned Excellent (very slight signs of wear)
Box & Papers: Included

Who It’s For

Buyers who value the Rolex brand, its resale strength, and the iconic Pepsi blue/red bezel will gravitate toward this model. The 40 mm case provides a slightly larger wrist presence than the Tudor’s 39 mm, and the Oyster bracelet adds a classic Rolex feel.

What We Would Change

The price is roughly 5.5 times the Tudor Black Bay 58 GMT for a functionally similar GMT complication. For most enthusiasts, the cost gap is the primary barrier, especially given the long retail waitlists that push many shoppers into the pre-owned market anyway.

The table highlights that the Tudor GMT models deliver the same core GMT function as the Rolex at a fraction of the cost, while the base Black Bay 58 shows that the GMT addition costs only about $500 over the non-GMT version. The Rolex, despite its larger case and iconic bezel, does not offer a functional advantage that justifies its 5.5 times price premium for most buyers.

Your Top Questions Answered

How much does a pre-owned Tudor Black Bay 58 GMT actually cost right now?
The live price for the black-dial GMT version is $4,695, and the black-and-burgundy bezel variant lists at the same amount, both verified on 5 Sept 2026 Bob’s Watches.

Is the Tudor Black Bay GMT a real alternative to the Rolex GMT-Master II?
Functionally, yes. Both watches use an in-house GMT movement with an independently-adjustable hour hand. The Tudor’s 39 mm case is slightly smaller, but it offers the same dual-time capability at a price that is a fraction of the Rolex.

How much more does the GMT complication add over the base Black Bay 58?
The base Black Bay 58 (blue dial) sells for $4,195, while the GMT-equipped version sells for $4,695. The GMT adds roughly $500 to the price, confirming a modest premium.

Does Tudor’s GMT movement work the same way as Rolex’s?
Both employ an independently-adjustable local hour hand, allowing the wearer to set a second time zone without moving the main hour hand. The Tudor uses the MT5652 calibre, while Rolex uses its own GMT calibre, but the user experience is essentially identical.

What condition and box/papers should buyers expect at this price point?
All five watches in this guide are listed as “Pre-Owned Excellent” with “very slight signs of wear” and include original box and papers. This level of condition is standard for the price tier on Bob’s Watches as of the latest check.

What We Would Buy

If we had to pick a single pre-owned piece that balances price, functionality, and collectability, the Tudor Black Bay 58 GMT (black dial) stands out. It offers the coveted GMT complication, a reputable in-house movement, and a 39 mm case that many find more versatile than the Rolex’s 40 mm. The inclusion of box and papers at $4,695 provides the security of provenance without the steep premium that comes with the Rolex name. For buyers whose budget stretches to the low-five-figures, the Tudor Black Bay 58 GMT (burgundy bezel) offers the same technical package with a splash of colour, making it the next logical step.
