Brellum, the independent Swiss watch brand founded by Sebastien Muller, has been specialised in the manufacturing of mechanical chronometer wristwatches that proudly bear the prestigious ‘Swiss Made’ label.
The latest addition to its COSC-certified product range is Wyvern GMT Chronometer. An ideal companion for globetrotters, this self-winding dual time-zone watch boasts a sporty-cool aesthetic. Showcasing the high standards of Swiss watchmaking, it has a 42mm diameter stainless steel case and houses the BR-893-GMT automatic calibre (ETA 2893/2 base).
Visible through the sapphire crystal caseback, this exclusive chronometer movement also boasts high-horology decorations like Perlage, colimaçonnage, Geneva stripes and blue screws.
The Wyvern GMT Chronometer has a multi-level dial to accommodate various indications with perfect legibility. Available in blue, silver or black color, the dial is finished with a sunshine pattern.
The dial is comprised of multiple layers. To start with, it has a central circle hosting all the four hands (hour, minute, seconds and GMT). It also has dotted markers placed as a pair of two for representing 12, 3, 6 and 9 respectively.
Immediate to the central part is a 24-hour dial ring for tracking the additional time zone. Surrounding the GMT (24-h) scale is a large dial ring with applied hour markers and minute track for indicating the primary time zone. Bordering the dial is a flange of same color with markings indicating from 5 to 60.
With a thickness of 10.9mm, Wyvern GMT Chronometer features a slim and compact design. This versatile watch comes with a rubber strap or stainless steel bracelet. Just like all Brellum watches, it is officially certified by the COSC and delivered with its official certificate.
