Supermarine 300M GMT Ember Red

The Supermarine 300M GMT Ember Red defines a travel-ready timepiece constructed in precious metals with 300 m water resistance and a GMT complication so you can track two time zones reliably.

If you move between zones or need a watch that endures daily wear, many designs sacrifice clarity or corrosion resistance. This model addresses that by combining a clear dual-time display with a corrosion-resistant precious-metal case and refined proportions that maintain presence without excess.

• 300 m water resistance for seawater exposure and active wear
• GMT dual-time function for straightforward tracking of a second time zone
• Precious-metal case construction for long-term corrosion resistance and finish retention
• Refined case lines and legible dial design for everyday readability
• Final quality inspection and water-resistance testing as a Maison Valderre selection

Unlike chronographs built primarily for split timing, this watch prioritizes travel utility and durability. Compared to conventional dress GMTs, its 300 m rating allows for more active use while retaining a considered aesthetic.

Maison Valderre subjects each selection to inspection and performance checks. If you want a dual-time watch that balances technical capability and considered design you can rely on, review the detailed specifications and service options to support your watch over time.
