British brand Bremont has unveiled the limited edition Bremont Waterman, a new GMT dive watch to its Supermarine collection. The chronometer-grade diver was tested by renowned free-diver and ocean conservationalist Mark Healey and is limited to just 300 pieces.

This is an extension of the Supermarine range

The Waterman incorporates a GMT hand and features deep-blue applied indices on the white metal dial. An extension, but modification to the Supermarine range, the Bremont Waterman uses the core S500 watch architecture but is fitted with an open sapphire backed 500m water-resistant case just like the Bremont Endurance watch that was released a few months ago.

The watch was tested by free-diver Mark Healey

It uses a 43 mm brushed stainless steel case that features Bremont’s characteristic Trip Tik three-part case construction. The three parts include a hardened steel bezel element, containing the sapphire crystal, a central body section, consisting of a titanium or DLC treated middle barrel and finally, the steel and crystal caseback.

In a strange irony, a watch associated with a free-diving enthusiast has a case fitted with a helium release valve. It is also fitted with an anti-shock vibration mount and scratch resistant sapphire uni-directional bezel.

The chronometer-grade movement is a modified ETA 2892-A2

The blue and white color scheme is used on the dial and bezel. The hands and indices are coated with SuperLuminova for optimum legibility underwater. The watch is powered by Calibre BE-93-2AE, a modified version of the self-winding ETA 2892-A2. A COSC-certified chronometer, it is fitted with a Glucydur balance, Nivaflex 1 mainspring, and has a skeletonized decorated rotor. This 4-Hz movement has a power reserve of 42 hours.

The watch is also available with a steel bracelet

The watch is fitted with a blue rubber strap or a Blue Kevlar with Red Stitch Strap. It is also available with a five-link stainless steel bracelet. A portion of the proceeds from the Waterman's sales will benefit Sustainable Coastlines Hawaii, a charitable clean water initiative too. The watch is priced at $5,995 (Approx. AED22,000).
