F.A.Q.s

Upon receiving the watch, please wind it. It is likely that the watch runs out of energy during the journey. Wind the watch by turning the crown for about 15 – 20 full turns clockwise. If you know your watch is battery, there is no need to wind it. If your watch has a screw-tight crown, release it by turning it anti-clockwise until it is loose. Then you can wind it for 15 – 20 times clockwise as mentioned. Once it is done, you can screw it tight by pushing the crown inside. Turn the crown clockwise and screw it tight back at the same time. By doing a manual winding of the watch, your watch will start to tick.

A2. If your watch is a quartz version, it means that the battery has been used up. Please change the battery. 

If it is an automatic watch, it is running on stored energy. It gains energy from human hand kinetic movement. When you do not wear it and it runs out of stored energy, it will stop. To make it tick again, you have to wind it for 10 – 12 rounds by turning the crown clockwise. To re-adjust the Day or Date back correctly, it depends on whether the crown is the one adjusting or it is recessed or button pusher. You can then adjust accordingly. For the crown, pull it out lightly once to adjust Date/Day (Most watches are like that). If you pull out the crown out twice, it will adjust Time. If it is a screw in crown, unscrew the crown anti-clockwise and follow the same instructions to adjust Date/Day and Time. 

A3. To set time, you need to unscrew crown anti-clockwise direction if you have a screw-in crown watch. You need to softly and slowly pull the crown out a little bit. The best way to do this is to use first and second finger and use finger knuckle as a lever in order to pull the crown out with as little force as possible. You can feel a little “click”! Now you can set the time by turning it anti-clockwise. This would turn the minute-hour hands forward until you set the right time. When time is set, push the button back and screw the crown clockwise for a few rounds to ensure it is screwed back tight.

A4. GMT means Dual Time Zone and it usually use a 24-hour clock instead of a 12-hour clock we normally use. GMT can be set with two time zones. A local minute-hour hand time and a GMT (sometimes red) arrow second time zone. 

To adjust time, please follow the instructions below: 

1. Unwind the crown anti-clockwise softly and slowly until it loosen up. There are two steps of pulling out the button stem. Do not exert too much force here and please make sure you do it lightly and carefully.

2. STEP ONE is for setting the GMT second time zone. STEP TWO is for setting the local time. Pull one-step out is to set GMT and date by winding the button clockwise and anticlockwise respectively. Pull one more step is for setting local time. Pushing the crown inward one step will bring it back to GMT setting. Pushing it two steps will bring it back to normal position and you can wind it back clockwise while pushing it back softly to secure the crown onto the watchcase. 

3. Set local time FIRST and then GMT SECOND time zone. When you set local time, GMT time will also be changed at the same time 

A5. A new battery will normally last for two years. Depending on time of the last replacement, you would probably need to change battery within two years. 

A6. To change date and time you need to do the following. If you have a screw-in crown like a Rolex, you need to turn the crown anti-clockwise for a few rounds until the crown is loose. Then you need to pull the crown out softly by using your thumb’s nail and first finger’s nail. Please do this softly to avoid breaking the stem. You should feel a “click” here. There are two steps when you pull the crown out. The first step is for setting the date (and Day if you have a Rolex Day-Date). The second step is for setting the local time (see Q2 and A2 for details). You can only set Date forward by turning the crown in one direction. When you are done with setting date and time, push back the crown and wind it clockwise for a few times to lock it. 

A7. A Screw-in crown will lock into the case of the watch when you turn the crown clockwise toward the watch case. It will tighten when it is screwed tight. Most Rolex watches use Screw-in crown. When you want to wind your watch, you have to un-lock the crown by turning the button anti-clockwise until you see the crown comes out of the watch a little bit, about 1.0 to 1.5 mm. Do not force the crown to come out cause it will easily break the stem link with the watch. When the crown comes out, you can then wind it, adjust time, date, day just like other watches. To lock it, slowly turn it and push it toward the watch until it is locked tight. NO need to apply extra force after it is tight! For most other non screw-in crown watches, you just wind it, adjust time, date, day without the need to un-screw the crown. 

A8. Recessed pushers are button that are designed in a way that the button is inside the watch body, mostly for appearance purpose. Many times, there are too many push buttons on the watch already and making recessed pushers will help to save space and makes it more desirable in looks. Usually, recessed pushers are for setting date, year or day, etc. Use a ball-point pen to push the recessed pusher all-the-way and release fully will make it change accordingly. Repeat the process until you set the right information. Do not push half way or release half way, it will sometimes cause the gear to change half way and make it show the wrong information and it might damage other mechanical parts in the watch’s movement.  

A9. The Daytona has chronograph buttons, which has a protective-screw lock for protection. This is a unique feature for Rolex Daytona. When you need to push the button, you need to un-wind the protective-screw to the level of the inside button, then you can push the button and press the button. Be sure to push it all the way and fully release it when pushing. Pushing halfway may cause it to stop half way and cause mechanical problems. 

A10. It is a scale on the dial. In fact, many sports version watches have it either on the rim or bezel. In conjunction with the second hand, it gives the speed of a moving object. A tachymeter takes a value determined in less than a minute and converts it into miles per hour. For example, a wearer could measure the time it takes a car to pass between mile markers on the highway. When the car passes the second marker, the second hand will be pointing to the cars speed in miles per hour on the tachometric scale.

A11. To avoid damaging the delicate mechanisms of the Valjoux 7750b1 movement you need to follow the instructions listed below to take care of it:

If your Valjoux 7750b1 has DATE function, DO NOT ADJUST the date when your time is between 10:00 to 3:00. It will damage the internal gears unknowingly if you do that. The BEST WAY is to manually adjust the time to 6:00 and then adjust the DATE after that.

If you are using the chronograph functions of the Valjoux 7750b1, always make sure that to start the stopwatch, you depress the pusher button on top and also to STOP the stopwatch, depress the same pusher button.
