User manual

Theorema is designed with water resistance of up to 5 ATM, which means it can withstand water splashes, can be worn in the shower and can be immersed in water while swimming. However, it is important to note that it is not suitable for deeper scuba diving.

Theorema is fitted with a Seagull TY2809, an automatic movement with a 36-hour power reserve and a balance frequency of 21,600 vibrations per hour (3 Hz). Seagull has been producing precise and reliable movements, worthy of note, for years, which is why we decided to use it in our first model.

Thanks to its automatic movement, Thema does not need a battery and runs on the kinetic energy produced by the movement of your wrist. To wind it, it is therefore enough to wear it or, alternatively, to turn the crown (without pulling it out) clockwise, 15 to 20 times at most. Due to various factors, such as temperature changes, wear or magnetism, the movement may gain or lose seconds depending on the situation.

To adjust the strap of your Thema you need to go to a watchmaker, a jeweller or an authorised service centre. Alternatively, you can use a specialised tool for removing links.

To set the time on your Thema, simply pull out the crown and turn it clockwise until you reach the desired time.
