Overview
Briston Clubmaster Diver Pro Automatic Watch with Black Dial.
Clubmaster Diver introduced an automatic dive watch to the sporting side of the Clubmaster line, with a screw-down crown at 4 o’clock. The Clubmaster Diver Pro measures immersion time with a notched unidirectional bezel and a ceramic insert graduated over 60 minutes. Its cellulose acetate and stainless steel case measures 44 mm and is 13.75 mm thick.
Made by Seiko, the NH35A automatic caliber powers the hours, minutes, central seconds, and date beneath a sapphire crystal. It runs at 21,600 vibrations per hour and has a 41-hour power reserve. The 316L case back screws down, and a few turns of the crown start the movement by hand.
A matte black ceramic insert with white lines and numbers frames the semi-gloss black dial, which has a tone-on-tone date window at 4 o’clock. Natural Super-LumiNova covers the hour markers, inner flange numerals, and hands. The black NATO strap measures 20 mm wide, can be changed by hand, and fastens with polished steel loops and buckles.

Questions & Answers
Who makes Briston watches?
Briston is an independent French watch brand founded by Brice Jaunet in 2013. Its first collection, the Clubmaster, brought tortoiseshell acetate, until then used in eyewear, to the watch case.
How is the dive bezel used?
At the start of a dive, turn the bezel until its zero sits over the minute hand. The unidirectional bezel turns one way only, so a knock can only shorten the time it shows.
Can it be used for diving?
It is rated 30 ATM, or 300 m, and has a screw-down crown at 4 o’clock. Screw the crown fully down before entering the water and rinse the watch in fresh water after exposure to seawater.
How long does it keep going off the wrist?
About 41 hours when fully wound. Wearing the watch keeps it wound. After a longer period off the wrist, unscrew the crown and turn it a few times to restart the movement.
Does the Superluminova fade?
Superluminova is a high-performance luminescent material that keeps the same charge and discharge cycle over the years, recharging each time it sees light.
