The new Graham watch offers 1000-feet water-resistance. Its case measures 47 mm in diameter.
On its left side, the case construction incorporates a steel with black PVD fast-action start/stop trigger, as well as a reset pusher featuring a “Clous de Paris” high-grip pattern. These features are designed to be extremely easy-to-use even when wearing diver gloves. The steel with black PVD bezel has a special rotating rim to be used for measuring decompression time. The steel or steel with black PVD case-back is reliably secured by 8 screws and demonstrates the Royal Marine crown-symbol.
The case construction is also equipped with a helium escape valve for prolonged deep-water diving.
The heart of the diver’s watch is an automatic bi-compax chronograph movement - Calibre G1734. Operating at a frequency of 28, 800 vibrations per hour, the 27-jewel movement, provided with an Incabloc shock absorber, gives an advantage of a 48-hour power-reserve.
The dial of the Graham watch offers supreme legibility even under no-light conditions as the hands and indexes are provided with Superluminova coating on the dial. The domed sapphire crystal with double-sided anti-reflective coating shields the dial.
The chronograph function is presented on the dial via a central seconds hand and a 30-minute counter at 9 o’clock. The 60-second counter is positioned at 3 o’clock. The date window is located at 7 o’clock.
The Graham Chronofighter Oversize Diver watch is secured to the wearer’s wrist on an integrated hypoallergenic black rubber strap equipped with a pin buckle.
Speaking about the price, the Turbo Tech version is available for 9,300 CHF, while the Deep Black version is a little more expensive at the price of 10, 500 CHF.
