Can I change the time by moving the hands of my watch anti-clockwise?

Changing the time by winding the hands backwards will not damage your watch but it can affect the date shown (for the MB range) and so we recommend that you change the time by moving it forwards, not backwards.

Can I over-wind my watch?

You cannot over-wind your watch; this applies to both automatically and manually winding a watch. Self-winding mechanisms continue working even after the mainspring is fully wound. If a simple mainspring was used, this would put excessive tension on the spring itself. To prevent this happening, a slipping clutch device is used on the mainspring so it cannot be overwound.

Do I need to wind my watch?

When you buy your watch, the movement will automatically start with just a few revolutions of the rotor, however it is recommended that the movement is wound fully with 30-40 revolutions of the crown, which will ensure maximum accuracy and power reserve. Your watch will need winding again if it is left for the power reserve to run down or if it is not worn consistently. (See “Why has my watch stopped?”)

How do I use the tachymeter?

To use the tachymeter to measure speed, you need to know how far a mile is from your starting point (where you will start the chronograph) so that you can stop the chronograph when you reach the mile mark. If you now read the position of the seconds hand against the dial ring it will tell you your average speed over the distance of 1 mile. To measure the distance, you need to know the speed at which you are travelling; start the chronograph and then stop it once the seconds hand has reached the number on the dial ring equivalent to the miles per hour that you are travelling at (eg 70 for 70 mph). This will tell you when you have completed 1 mile. Watch the Tutorial Video here.

How do I use the telemeter?

To use the telemeter on the 1918: start the chronograph using push button A (top button) when the event is seen and when the sound is heard push button A once more, to stop the chronograph. The telemeter scale value at which the chronograph seconds hand is pointing is the approximate distance in miles between your position and the event.

How do I wind my watch?

If your watch has a screw-down crown (Jaguar MKI, Supermarine, Airco, SOLO-32 & Boeing models) you will need to unscrew it in an anticlockwise direction until you hear a small click; you are now in the winding position. If your watch has a pull-out crown (ALT1, MB, U-2, Jaguar MKII and MKIII, SOLO models) it is already in the correct winding position. Wind your watch by rotating it in a clockwise direction. NB the original ALT1 and SOLO models had screw down crowns, this has since changed.

How do you set a World Timer watch?

The World Timer function on the ALT1-WT can be operated using the crown at the 8 o’clock position. It is straight forward to use and its purpose is to help you keep track of time in different time zones or cities around the world. Simply turn the 8 o’clock crown clockwise or anticlockwise depending on the time zone that you wish to select. If you wish to know the time in Tokyo, for instance, simply rotate the internal ring so that Tokyo is in the 12 o’clock position and read the time using the GMT hand.

How do you use the 12 hour hand?

First ensure that the local time is set on the watch. Then pull the crown out to position II and rotate it anti-clockwise to set the 12 hour hand to the 12 hour markers on the dial ring. For example, if you set the watch to 1.00pm local time and your second location is 5 hours ahead, you would set the 12 hour hand at 6.00 pm.

What settings should I set my watch-winder to for my watch?

We recommend 750 rotations per day at a medium setting for most Bremont watches.
