The Bremont MBIII/WH GMT is a limited anniversary version of the MBIII, created to mark ten years of Bremont’s partnership with Martin-Baker. Bremont announced a production limit of 310 pieces. Its white dial, ejection-seat triangle and engraved seat case back distinguish it from the standard MBIII; the brand now lists the MBIII as retired from its catalogue.
This is a reference-based overview, not a report of physical handling. The specifications below are those Bremont publishes for the standard MBIII unless explicitly identified as anniversary-edition details.
What is the Bremont MBIII GMT 10th Anniversary?
The anniversary watch is identified as the MBIII/WH GMT chronometer. Bremont framed it as a decade-of-partnership edition, looking back to the first MB watch, released in 2009. The anniversary is historical, not a current release. Bremont’s announcement set a production limit of 310 pieces; that figure describes the announced run, not how many sold or how many remain available. Bremont’s MB collection page describes the anniversary design, while its historical announcement identifies the model and edition limit.
How is the MBIII/WH different from the regular MBIII?
The edition-specific details Bremont names are cosmetic and commemorative. The company describes the MBIII/WH as a white-dial MBIII with an ejection-seat triangle and an engraved seat case back. Bremont’s standard MBIII product page, by contrast, specifies a black metal dial. The sources do not establish that every other standard-model detail carries over unchanged to every anniversary example.

What are the standard MBIII specifications?

How does the GMT and bezel work?
Bremont describes the MBIII GMT movement as allowing simultaneous timekeeping in two time zones. The 24-hour GMT hand provides the second-zone indication, while the inner bidirectional Roto-Click bezel is another timing reference. Together, these features make the MBIII a dual-time, pilot-style watch. The available product information does not provide a setting sequence for the MBIII/WH; consult the manual for the specific watch before changing the time or bezel.
What does Bremont say about MB testing?
Bremont attributes the MB line’s testing programme to demanding aviation conditions. Its historical MBIII announcement describes tests involving salt fog and humidity simulation on an aircraft-carrier deck, altitude, temperature endurance, vibration and live ejection. These are the manufacturer’s descriptions of its programme, not independently witnessed or reproduced test results. Read Bremont’s MBIII announcement.

Is the Bremont MBIII still available?
Bremont currently labels the standard MBIII as retired from its catalogue. That confirms its catalogue status, not whether new-old-stock, retailer, reseller or private-sale examples exist. No current price or live inventory is established here, so check current listings directly rather than treating the 310-piece production limit as a measure of present-day scarcity or value.
For a prospective purchase, verify the exact reference, seller and provenance, and inspect the watch’s condition and service history. Bremont’s standard page lists a 22 mm lug width, but confirm strap fit on the actual MBIII/WH before ordering; the listing does not establish the fit of every anniversary example or strap end.
