Mechanical watches work on power reserve, which means that energy is saved in the barrel spring and continuously is distributed into the gears of the mechanism to establish a smooth operation of the watch.
The average mechanical watch lasts for about 38 hours, although all watchmakers do recommend to wind your watch approximately at around same time every day in order to give it the energy required for the watch to maintain highest functionalism during the 24 hours.
If the watch is not worn daily; but you want to avoid setting it up daily, we advise to keep winding it before the power reserve is consumed, which is on average 38 hours.
If a mechanical watch requires manual winding different is the story for an automatic watch. The wrist movement will produce the energy that is slowly distributed to the barrel spring through the oscillating mass to ensure a smooth operation. Thanks to this process you do not need to manually wind an automatic watch.
To keep the watch in constant operation our advice is to wear the watch everyday or get yourself a watch winding case. This will help avoiding having to adjust time each wear.
What to do if your watch stops? The finest way to bring it back as evenly it's by turning the winding crown around 30 times.
]]>The strap also requires all your care and attention. Leather is a living material that is delicate and sensitive. We would draw your attention to the fact that exposure to moisture and skin care products may accelerate the aging of your watch strap.

]]>Understand the meaning of ATM.
30m (98.4ft) = 3 ATM = Splash resistant. Ok for rain, hand washing splashes, other occasional contact with water, but not intensively and not for long periods. 50m (164ft) = 5 ATM = Suitable for swimming, fishing, other outdoor activities. 100m (328ft) = 10 ATM = Fit for snorkeling and other prolonged contact with water, but not for scuba.
All Theorema watches are 3 ATM.
Please make sure that your watch complies to the appropriate level of water resistance.
We do recommend that if the watch is not kept in normal room temperatures or if it's kept for a prolonged period of time in very humid conditions to have the Theorema official service centre in Germany have a check of all it's part in case of any rust.
Want to take it a step further to protect your watch? Make sure at all times that the crown is always pushed back against the case (1st position), especially after setting the time or adjusting its functions.
If water accidentally enters inside the case or if you notice any trace of moisture let it dry, wipe it down using a cloth, and contact us in order to send the watch to our service centre in Germany.
Avoid contact with sea water. Avoid contact with any chemicals. Avoid contact with soaps. Avoid taking a shower with your gentleman watch. We highly suggest that you read the User Guide.
