The model in detail

In coverage dated October 16, the Ressence TYPE 10 DN introduces the new RW04 movement with two mainspring barrels. Oil fills the upper display chamber, while the movement runs in a separate air chamber; a magnetic coupling transfers energy between them.

The 41.5 mm titanium case has a blue DLC coating. Alongside hours and minutes are a second time zone and an oil-temperature indicator. Production is limited to 100 pieces; MONOCHROME reports deliveries from November 2026 and an announcement price of CHF 45,000 before taxes.
