Manual winding is always necessary for a mechanical watch (hand-wound or automatic). Before starting up for the first time and after long periods of inactivity, it is not sufficient to wind an automatic watch simply by wearing it. To put your watch into operation, you should wind it fully. This is done using the crown. 30 - 40 turns are the rule. With an automatic watch, the spring cannot be overwound - as is often claimed - as it is protected by a slip clutch. Manually wound watches may only be wound until resistance is felt.
To set the time and date, pull the winding crown out to the first click position (after unscrewing the screw crown). This position is usually the correct position for the quick date setting. Set the date to the date of the previous day by turning the crown and then turn the hour hand forwards over 12 o'clock using the second crown position (pull the crown out again to the second click position). If the date jumps forward by one day, the watch is set to the beginning of the current date. If it is the afternoon, you must turn the hour hand past 12 o'clock again, i.e. to "afternoon". Never set the date on mechanical watches when the hour hand is between 9.00 p.m. and 3.00 a.m., as this can damage the movement.
Rate accuracy: You can influence the rate accuracy of your mechanical watch to a certain extent. When you take the watch off, you can do this in different positions. Crown up means the watch runs slower, as the balance is in a suspended position and the resistance is greater. Dial down means the watch runs faster, as this is where the least friction occurs. Observe the rate behaviour and try out the different positions (i.e. dial up and crown down). In this way, you can achieve rate deviations of up to 2 seconds/day. Please note that you have a mechanical watch with a rate deviation of up to 60 seconds per week within tolerance.
We recommend the use of a watch winder, especially if you are in the fortunate position of owning several watches. You will find a large selection of these useful helpers for automatic and hand-wound watches in the watch winders section.
Chronograph function: top pusher = start/stop function, bottom pusher = zero setting - reset. The chronograph may only be reset to zero after it has been stopped. The two push-buttons must never be pressed simultaneously, as this may damage the chronograph function.
Water resistance: Always keep the crown pushed in or screwed in. Never operate the pushers under water and never pull or unscrew the crown. The water resistance should be checked every two years by a specialised watchmaker. Most jewellers also provide this service on site. If water ingress or even just condensation is visible on the inside of the watch glass, we strongly recommend that you visit a watchmaker immediately.
- "water resistant" means splash-proof. The watch is not water resistant
- "water resistant", 30 m, means minimal contact with splashing water possible, e.g. when washing hands
- "water resistant", 50 m, means contact with water is possible, e.g. when showering and bathing
- "water resistant", 100 m, means swimming and snorkelling are possible
- Only watches labelled 100 m (10 ATM) are suitable for swimming or water sports. The standard for diving watches is at least 200 metres (20 ATM). Only these watches are suitable for diving. Good to know: There is no guarantee of water resistance. Please refer to the operating instructions for your new watch.
We wish you lots of fun and long-lasting pleasure with your new watch from Ralf Häffner Jewellers!
