The Bremont Supermarine Full Ceramic Tactical Black suits you if you want a ceramic-forward case, 500 m water resistance and a helium escape valve. The TUDOR Pelagos FXD M25707B/26-0001 suits you if you want a titanium case, fixed strap bars and a design rooted in French Navy underwater navigation, with a longer power reserve. Both are capable dive watches, and the published specifications point in different directions. They do not settle comfort, long-term wear or value, which you need to judge hands-on and with current prices.
The choice comes down to one question: do you want the Bremont’s 500 m ceramic-case specification, or the Pelagos FXD’s titanium construction and navigation-oriented bezel design?
Which priorities point to which watch
- Choose the Bremont if your main criteria are the deeper stated water resistance, a helium escape valve, a ceramic bezel insert and case material, and a rubber strap that works with quick release.
- Choose the TUDOR if you prefer titanium over ceramic, want fixed strap bars, care about the bezel’s history as a navigation tool, and want the longer stated movement reserve.
- Neither choice is settled by the official pages alone if you are deciding on comfort on your wrist, scratch resistance in daily use, or price-for-value. Those need your own testing and current pricing.
Specifications at a glance
The figures below come from the two manufacturers’ official product pages, accessed 9 October 2026. Where a value is not published, the table says so rather than estimating it.

The two cases are close in diameter, but the length and thickness figures use different labels. The Bremont’s “length” and the TUDOR’s “lug to lug” are not the same measurement, so the table is a guide to the spec sheet rather than a direct fit comparison. Try both on your wrist before judging size.

Case construction: ceramic versus titanium
The most visible difference is the material story. The Bremont is built around black ceramic. Bremont describes the case as a single block of ceramic with a titanium movement container, and it says the ceramic is extremely scratch resistant. That is a manufacturer’s material claim, not a head-to-head test against TUDOR’s titanium. Bremont also publishes two process figures on its product page, dated 2026: a 23% shrinkage during sintering and a sintering temperature of 1,450°C. These describe how the case is made, and they do not measure how the watch performs once you own it.
TUDOR’s Pelagos FXD uses satin-brushed titanium, which is lighter and more commonly associated with comfort on the wrist. Titanium also has a different surface behaviour: it shows fine marks in a way that many owners find acceptable and that the brushed finish is designed to disguise. No comparable test in the reviewed sources establishes which material resists scratches better in real use, so treat the claim as the manufacturer’s position rather than a verdict.
Water resistance and the helium escape valve
The Bremont is the stronger specification on paper. It is rated to 50 ATM, which the brand equates to 500 m, and it includes an automatic helium escape valve. That valve matters for saturation diving, where helium can enter the case and must be released during decompression. The TUDOR is rated to 200 m (660 ft) and does not list a helium escape valve.
Rank #2
- Self-contained ever glow tritium-vial lamps; Titanium case is light, strong, and hypoallergenic; high water resistance feature set.
- Tritium vials are not inset but 80% above the face surface; This makes them visible from the edges Not just from above.
- Large, substantial, 50 mm high-vies design; Scratch-resistant sapphire crystal glass & crystal interior is anti-reflective coated.
- The gmt models include a daylight ring Plus an additional hand for tracking a second time zone
- What's included: Comes mounted with custom T.P.R. Band, 1x military-grade Thermoformed travel case.
For recreational diving, 200 m is well beyond the depths most divers reach, so the difference matters mainly if you intend to use the watch in very deep or professional contexts. If you do, confirm the depth rating and any gas-related features against the requirements of your own work or certification, rather than assuming a higher number is always the better choice.
Bezel design and the navigation question
The two watches are built around different bezel philosophies, and this is where the TUDOR’s background matters most.
Bremont: unidirectional rotating bezel
The Bremont uses a unidirectional rotating bezel with a ceramic insert, which is the standard arrangement for timing dives: you set the bezel and watch the marker count down the elapsed time.

TUDOR blue Pelagos FXD: bidirectional navigation bezel
The original blue Pelagos FXD was developed with the French Navy’s combat swimmers, the Commando Hubert, for underwater navigation. Its bezel is a bidirectional titanium bezel with a ceramic disc and a retrograde graduation running from 60 to 0, which is intended for navigating in successive stages rather than timing a dive. TUDOR states on its collection page that this 120-notch bezel does not correspond to the ISO 6425:2018 divers’ watch standard, because it serves the underwater-navigation method. In TUDOR’s words:
“The Pelagos FXD is a technical watch that meets a unique set of specifications that was developed for underwater navigation in conjunction with the French Navy’s combat swimmers, the prestigious Commando Hubert.”

This is a brand statement without a named individual speaker. It describes the design purpose, not an independent assessment of how well the bezel works.

TUDOR black Pelagos FXD: a different bezel
The FXD family is not one bezel. The official page for black reference M25717N-0001 describes a unidirectional 60-minute diving scale, which is the conventional arrangement. Before you describe a Pelagos FXD’s bezel, identify which reference you are looking at, because the navigation-specific design applies to the blue model.
Movement and power reserve
TUDOR’s Pelagos FXD uses manufacture calibre MT5602, which carries COSC certification and offers approximately 70 hours of power reserve, according to TUDOR’s product page. The Bremont is automatic with a stated reserve of approximately 50 hours, but its product text does not name the calibre. A longer reserve helps if you tend to leave a watch off the wrist for a few days, but it is a stated figure from each manufacturer. It is not a measured comparison.

Bremont: quick-release rubber strap
The Bremont ships with a black rubber chevron strap, a pin buckle and a quick-release system. If you want to swap straps, the quick-release arrangement is the easier route, provided the replacement is made for this 22 mm lug width and quick-release fitting.
TUDOR: fixed bars and a navy fabric strap
The FXD name refers to fixed strap bars, which are machined into the case rather than using spring bars. Fixed bars are part of the design identity: they give a secure attachment and a clean profile, but they limit which straps you can fit. TUDOR includes a navy fabric strap with a self-gripping fastening and lists a navy rubber strap as included. Any replacement strap has to be designed for fixed bars, so do not assume a standard 22 mm strap will work.
A note on aftermarket straps
Both watches have a 22 mm lug width, but a nominal width does not confirm compatibility. The two use different attachment arrangements, so check that a strap is made for the specific attachment type before buying one.
What the official figures cannot tell you
- Comfort. Case weight, shape and strap feel all affect wear, and the sources reviewed do not offer a comparable complete-watch weight for the TUDOR, so the weight comparison is incomplete.
- Durability. The sources do not contain an independent test comparing scratch resistance or long-term wear between ceramic and titanium.
- Value. Current retail prices, stock levels and authorised-seller status were not established in the sources reviewed. Compare prices directly with the brands or their authorised retailers, and treat any secondary-market listing with care.
- Warranty. TUDOR’s five-year transferable guarantee is stated on its page, but the terms vary by country. Bremont’s warranty terms were not stated in the source reviewed.
How to decide
- Start with how deep and how often you will dive. If you are a recreational diver, 200 m is well beyond normal use, and the extra depth rating of the Bremont may not be the deciding factor.
- Decide whether you need a helium escape valve. If you do not, the Bremont’s valve is a specification feature rather than a daily benefit.
- Decide what kind of bezel you want. A unidirectional timing bezel suits most dive use; the TUDOR blue’s bidirectional navigation bezel suits you if you care about its underwater-navigation design.
- Decide on the strap system. If you want easy strap swaps, the Bremont’s quick-release arrangement is the simpler option. If you prefer the fixed-bar look and do not mind limited strap choice, the TUDOR suits you.
- Try both on your wrist if you can, paying attention to size, weight and how the case sits, since the two sets of dimensions use different labels.
- Check current prices and warranty terms in your country before you buy.
