C by Romain Gauthier is a manual winding timepiece. 
It is wound using the crown at 2 o'clock.

1.    Ensure the crown is pressed in
2.    Turn the crown in the direction of the arrow

Important: To prevent overwinding, there is an in-built block that the wearer will feel the crown block when the watch is fully wound. Once this feeling is reached, do not try to wind any further.

1. Pull out the crown

2. Turn clockwise or anticlockwise

The time is set on C by Romain Gauthier using the small crown on the caseband at 2 o'clock. 
To set the time, gently pull out the crown and turn clockwise or anticlockwise to the correct time. When the correct time is set, push the crown back in towards the case. 

Important: Do not pull the crown out if the watch is wet or in water.

The mechanism employs a snail cam that performs a double function: It touches and stops the balance wheel when the crown is pushed back in, the snail cam makes a turn, with its increasingly wide form giving the balance an impulse to help it start beating again. 

Water resistance 
Your C by Romain Gauthier is water resistant to a static 50 metres/160ft. However, vigorous swimming and diving should be avoided as moisture may be forced past the water-resistant seals.
