Motion

ONS has an ETA 2824-2 Automatic movement with 38 hours of power reserve.

Anti-oxidant rhodium protection on the bridges and movement plate.

25 jewels and 2 anti-shock systems for the steering wheels.

Swiss movement, with a diameter of 25.60 mm and 4.6 mm in height.

The frequency of the flywheel is 28'800 beats/hour.

Oreto has modified the original movement to offer an exclusive timepiece that meets both the brand's design requirements and quality standards.

Average accuracy tolerance of -4/+6 seconds per day.

Glass

Flat sapphire crystal with double anti-reflective treatment.

Thanks to its chemical properties, Oreto sapphire crystal is a very hard and resistant component (Vickers hardness equal to 2300).

It is the second hardest component after diamond. For comparison, it is also seven times harder and stronger than hardened steel.

It gives the watch properties such as extreme shock resistance and good readability of the dial and hands thanks to its transparency.

Box

The case is made up of several parts, all of them made of 316l surgical steel.

Box size:

  • Diameter of 40 mm
  • Log to log 45mm
  • Height 10.5mm
  • Weight 55.4 g

In addition to being an important element from a design perspective, it also protects the movement from impacts, dust, and gases, among other things.

Thanks to this, you can enjoy your most daring adventures with your Oreto.

Oh... and don't worry! It's water resistant to 100 meters.
