A free scan shows the junk files, broken settings and background clutter dragging Windows down - then fixes them in one click.Free scan · Windows 10 & 11The Brellum Wyvern GMT/2 combines a COSC-certified automatic movement with a 24-hour GMT hand, a 42.3 mm steel case and a stated 100 m water-resistance rating. Brellum’s black-dial listing, SKU WGMT.237, showed a price of CHF 2,157.99 and availability on October 8, 2026; that dated listing includes a steel bracelet and several accessories. This is a specification- and ownership-focused evaluation, not a report of physical testing or wrist wear.
What movement does the Brellum Wyvern GMT use?
Brellum specifies its BR-893-GMT automatic chronometer, with a 42-hour power reserve, 28,800 alternations per hour, 21 jewels, instantaneous date, stop seconds and a central 24-hour GMT hand. The company identifies the movement as COSC-certified on its Wyvern GMT specifications page.
Monochrome Watches reports that the BR-893-GMT is based on the ETA 2893/2. That provenance detail comes from Monochrome’s independent hands-on article; Brellum’s current technical summary does not name the base caliber. The ETA-base description should therefore be understood as independent reporting, not as a specification stated on the current official product page.
Is the Wyvern GMT COSC certified?
Yes. Brellum describes the BR-893-GMT as officially COSC-certified. That is the manufacturer’s model specification; the available sources do not provide independent verification of an individual watch’s certification. The black-dial WGMT.237 listing says a COSC certificate is included.

Brellum also describes additional checks after assembly, including water-resistance, function, reserve/chronometer-mode and simulated-wear checks. Its quality commitment page says the operating reserve and chronometer mode undergo a “46-hour verification.” This is the company’s account of its quality process, not an independently observed test of a particular Wyvern.
How big is the Brellum Wyvern GMT?
Brellum lists an approximately 42.30 mm case diameter and 10.90 mm total thickness. The black-dial listing gives a 45.00 mm axis-to-axis measurement, a useful companion figure for considering how the case may span the wrist. The listing specifies a wrist range of 15–21 cm.
