Trident Seal Mach I

The Trident Seal Mach I is an uncompromising 41mm dive watch built for serious enthusiasts. Engineered around the proven SKX007 platform, it features a PVD-coated black steel case with sapphire front and rear crystals—domed, anti-reflective coated for clarity in any condition. The all-black dial is punctuated by gold accents, with blue lume on the dial and luminous green hands for low-light readiness. Powered by a reliable Seiko 24-jewel automatic movement, it delivers precision and durability. The screw-down crown at 4 o'clock locks in a 200m water resistance rating, making it capable for serious diving and everyday wear. Choose between a PVD-coated stainless steel bracelet or Seiko's classic rubber dive strap—both engineered for comfort and performance.
