The case is crafted with a refined elegance, featuring a subtle arched side profile that enhances both the sleekness of its appearance and the comfort on the wrist. This thoughtful design balances aesthetics with wearability, ensuring a graceful fit for everyday use.
We've successfully maintained a thickness of just 10.7mm, even with a 1mm dial and a relatively thick movement. The case has a 40mm diameter and a 46mm lug-to-lug length, making it exceptionally comfortable on the wrist.
The watch features a Chevé Box sapphire crystal. The primary advantage of this design is the generous view it offers of the dial, along with a sleek, thin profile for the watch.
The caseback is screwed directly into the lugs to keep the thickness as slim as possible at just 10.70mm. The sapphire crystal features a generously wide opening, allowing the movement to be fully showcased in all its beauty.

Our feuille hands (or Leaf) are made from steel and fully mirror polished. The shape at the base is inverted to give a "blade like" style. They are a true statement of understated elegance.

Our "Prestige" movement

Based on the renowned Swiss ETA Unitas 6498-2, our custom movement undergoes a complete overhaul by our precision partner in Glashütte, the birthplace of German watchmaking. The custom 3/4 bridge, mainplate and balance bridge are meticulously beveled and polished to highlight their unique shapes, drawing inspiration from vintage pocket watch movements and classical watchmaking. Adorned with gold perlage and Geneva stripes, it gleams with the same brilliance as the mirror-polished steel screws and ratchet-click system. The elegant handmade finishes make both the front and back sides of the OAN.GIO a visual delight. The power reserve is 56 hours.

Numbered and limited to 5 pcs per model.

Based in Ho Chi Minh City, Dat has been handcrafting premium leather straps for watch collectors for years. His dedication to quality and his love for his craft embody everything OAN.GIO stands for.
