Bonest Gatti Skeleton Automatic Watch, 45mm

The Bonest Gatti Skeleton Automatic Watch puts its movement on display through a square 45mm case and an open dial. Two finishes cover a polished steel case with red accents and a matte black case with green accents, both on Italian calfskin.

Why It Stands Out

• An openworked skeleton dial shows the balance wheel turning at the center of the watch.
• The automatic movement winds itself from the motion of your wrist, with no battery to replace.
• A power reserve indicator shows how much wind is left, and the movement holds 42 hours.
• Anti-glare sapphire crystal resists the scratches that mark softer glass.
• The caseback is engraved rather than stamped, with an open window onto the rotor.

Fit and Wear

At 45mm square and 15mm thick this is a large watch with real presence, so it wears best on a medium to broad wrist and over a sleeve rather than under one.

Colin's Take

Choose this if you want to watch a mechanical movement work without paying four figures for the privilege. Red on polished steel is the dressier of the two, while the matte black and green reads sportier.
