SLEEK TRI-COMPAX DIAL
The Swiss Automatic Movement ETA Valjoux 7750 6-hand and its 6/9/12 tri-compax arrangement with day/date complications as well as the 60-0 rotating countdown bezel allows the Navygraf Chrono to benefit from various features.
Our design team has carefully worked on a sleek two-tone dial and bezel that offers contrast and balance. The colour white is preferred to accentuate the legibility of all the complications.
SIGNATURES NAVYGRAF AND SAPPHIRE COUNTDOWN BEZEL
The hands and the second hand, offering increased legibility in all circumstances, as well as the indexes in the shape of "exclamation marks" are the signatures of the Navygraf since its inception.
Scratch-resistant, bi-directional sapphire bezel with 0 to 60 minute countdown graduation.
CURVED, BEVELED SAPPHIRE CRYSTAL
The Navygraf Chrono features a high-quality beveled domed sapphire crystal that is 1.80 mm thick, offering better readability, increased strength and a decidedly vintage look.
TIN BOTTOM
The 316 L steel caseback is engraved with the historic YEMA coat of arms at the hydraulic press and is 10 BAR waterproof.
MULTI-LANGUAGE DAY INDICATOR
The Navygraf Chrono is equipped with the ETA Valjoux 7750, with indication of the day of the week in French/English (other languages available on request) and the date at 3 o'clock on the dial.
MOVEMENT ETA VALJOUX 7750
This Swiss chronograph movement, renowned for its precision and reliability, features hours, minutes, seconds in the centre and an automatic ball-bearing winder. Equipped with 25 jewels, it beats at 28,800 vph with a 48-hour power reserve.
SUPER-LUMINOVA GRADE A
Upgrade from Super-LumiNova Grade Standard to Grade A for enhanced legibility and easy reading of the three time zones in any situation. The GMT bezel, with its sapphire insert combined with Super-LumiNova, required a special, innovative design to offer day/night visibility even in the dark.
