Q1. WHAT IS THE FIRST THING I NEED TO DO UPON RECEIVING THE WATCH?
A1. 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.
Q3. HOW DO I SET THE 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.
Q9. I HAVE A ROLEX DAYTONA WITH VALJOUX 7750B1 MOVEMENT WITH FUNCTIONAL CHRONOS, HOW DO I USE THE STOPWATCH FUNCTION?
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.
Q11. HOW DO I USE THE STOPWATCH FUNCTION ON VALJOUX 7750B1 MOVEMENT TO AVOID DAMAGE TO IT?
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.
REMEMBER: START & STOP is TOP Pusher Button
ONLY after you STOP the stopwatch, then you depress the lower pusher button to RESET the stopwatch function. DO NOT DEPRESS the lower pusher button when the stopwatch function is running. ONLY Depress the lower pusher button after you STOP the chronograph.
If you follow the instructions carefully, your watch will last you a long time. Naturally watches may not last a lifetime since they aren’t made to COSC standards and neither are they SWISS GENEVE made or stamped. Remember a replica is always a replica but do enjoy them as at a fraction of the cost, these cosmetically perfect replicas are a joy to wear, aren’t they?
Some additional 7750/7750b1/7753 Valjoux Movement Information
*Please read them before u play with your watch that has above movement
1. How do you set date on 7750 or 7753 or 7750b1 or any movt with date chrono/ automatic?
Do not activate the chrono until you have done all these steps as mentioned
When you receive your piece, please remember to handwind the piece for about maybe 50 rounds, so to generate enough power reserve. Then you shake the piece like a "mad cow" for 3-4 minutes to generate more power reserve (If necessary)
Then pull the crown out to adjust the hour hand manually to determine when is am/pm. See the date change - then you will know when is am/ pm. Make sure you know when is am/ pm before you proceed
Make sure you do not adjust the date between 10pm-3am ever!!! Do not ask me why because it just works this way. if you adjust between 10pm-3am, the date will jam or go half way.
After u have confirmed the am/ pm…..u can adjust the crown to get to the desired date you want.
As for the timer hand to reset back to zero, it is pure luck….u may have perfect reset, or less than perfect reset. My Genuine Rolex Daytona did not reset back to zero after 3 months. By the way, make sure everytime you activate chrono, you have enough power reserve. Have fun!!!
