What to know

The Reef GMT Green/Gilt applies warm gold-coloured details to Formex’s modular travel watch. Its 42mm steel case surrounds a green gradient dial, matching ceramic 24-hour bezel and central GMT hand. The bidirectional 48-click bezel can be removed without tools and exchanged with other Reef GMT or 42mm Reef bezels, making it possible to alter both the watch’s appearance and its timing scale.

Inside, the COSC-certified Sellita SW330-2 automatic calibre runs at 4Hz and delivers 56 hours of reserve. The case is 11.4mm thick, approximately 47mm lug-to-lug and rated to 300 metres, with sapphire crystals and a screw-down crown. Applied markers and hands carry BGW9 lume, while quick-release straps and Formex’s fine-adjustment clasps support daily fit changes.
