SharpNaut
The SharpNaut, sporty with an integrated rubber strap
The SharpNaut pairs a brushed and polished steel case with an integrated textured rubber strap that extends its lines. Its raised, textured dial carries luminous Arabic numerals, legible by day and in the dark. Two moods: a deep brown dial on rose-gold steel, or a light blue dial on silver steel, that of the SharpNaut Tiffany.
The SharpNaut measures 43 mm across but only 11 mm thick: it stays slim under a cuff. Its Seiko NH35 automatic movement, visible through the see-through caseback, winds itself as you wear the watch and holds about 41 hours of power reserve. Scratch-resistant sapphire crystal. Expect ¥44,800.
The SharpNaut is for those who like large, comfortable sports watches that stay on from morning to night. Each piece is hand-assembled in our Paris workshop, then checked and adjusted before shipping. Fancy another combination? Discover Create my own watch.

Frequently asked questions
Is 43 mm too big for my wrist?
Not necessarily: at 11 mm thick and with an integrated strap that follows the wrist, the SharpNaut wears more easily than its diameter suggests. Compare with a watch you already own, or write to us with your wrist size: we will advise you.
Is the dial legible in the dark?
Yes: the indices are luminous. They charge in the light and stay visible for a while in the dark.
Does the SharpNaut need a battery?
No. Its Seiko NH35 automatic movement winds itself with the movements of your wrist. If you do not wear it for about two days, it stops: wind it with the crown and set the time again.
