The name RESSENCE is a neologism assimilating the words renaissance and essence. Renaissance stands for the rebirth of what is essential to a watch, to display time. RESSENCE brings a contemporary evolution of time representation using the same universal cognitive patterns learned to read time on a traditional watch.
All Ressence watches undergo rigorous quality control in compliance with the highest standards of the Swiss
watchmaking industry.After being pre-tested by our suppliers in Switzerland, the entire watch cased-up is
controlled internally over a period of 500 hours. The R500H - RESSENCE 500 Hours - takes place in our
headquarters and consists of the 6 following operations.
Rating Regularity Control
We verify the perfect rating of the regulating organ. The balance spring assures equal oscillations and determines the precision of the watch. The measurement is made in 6 different positions, simulating average wearing conditions. The watch is monitored fully wound and after running for 24 hours.
Water Resistance : 1 to 10 ATM
We ensure our watches are protected against any water intrusion. An air test checks the water-tightness of the gaskets, the seals and the bonding of sapphire crystals on each watch. Watches are placed under pressures ranging between 1 to 10 atmospheres according to the model’s specifications.
Power-Reserve Control : 36 hours
We test and guarantee the 36 hours power-reserve in 3 different positions. Watches are also wound on a Cyclomotion during 8 hours. This operation tests the good winding of the watch by the oscillating weight.
We control the resistance to shocks. We place the watches loosely in a box running on the Cyclomotion in order to simulate the small shocks a watch undergoes under normal wearing conditions.
Temperature Resistance : 5°C to 45°C
We control the functioning of the watch under extreme conditions. The special alloy that composes the balance spring is very sensitive to temperature variations. Its dilatation can modify its regulating action and thereby affect the reliability of the watch. Furthermore the oil used in the TYPE 3 and the TYPE 5 is also sensitive to temperature variations. We test the seven bellows used in the watch to compensate for the oil expansion and contraction. After being placed in an oven at a temperature of 45°C the watch is chilled to 5°C.
We control each of the visual aspects of the watch: case, case back, dial, straps, buckle or folding claps are checked under a UV light and by magnifying glasses in order to guarantee a flawless watch in terms of aesthetics default or scratches.
