Rolex YachtMaster One of the hour insignias fell off inside my Rolex replica. I need to open up and re glue. How do I do this?

about 25 dollars its fake

Replica watches are all made in one Chinese town. The parts are pressed, not machined. They dont last long and cant be repaired.
Go online and buy another replica (the best ones are around $200!)

Yes, approximately 95% of Rolex replicas do have Rolex crown stamped on winding crown.

The Rolex yachtmaster is an automatic watch so needs no battery.IF the watch is a genuine Rolex then it needs to, be seen by a Rolex watchmaker to estimate.
www.rolexrepairs.co.uk will provide a free estimate,or give them a call the watchmakers will be happy to advise you.

mcdevito75 here, The answer is no, Rolex watches do not operate with a battery. Most Rolex watches are Automatic winding with the motion of your wrist / arm. Of course if you leave your Rolex on the dresser for say 30 hours, it will run down, simply hold the watch in your hand and with a gentle rocking motion say from 6--to 12 O'Clock for about 30 seconds, this will give your automatic Rolex an initial wind up, from there you just wear the watch and it will continealy wind itself. You may also have the non automatic Rolex in which case you would have to wind it dailey. If your Rolex will not run at all no matter what you try, Check out the repair service directory here at fixya, bottom of the page click on repair service directory then watches.

I have examined the Rolex web site and it did not appear to have any downloadable instructions.

The best I can suggest is that you go to the Rolex web site (www.rolex.com/en/index.jsp) , select "site map" from the options at the bottom of the screen.

Now select "store locator" and find the nearest Rolex dealer to you.

I feel sure that they will be happy to explain all the settings and might even be able to give you a copy of the user instructions.

Rolex does not engrave the case back. If it says 24 hours at Daytona, or wording like that, the watch is not real... It's a fake, or as we say more kindly.. It's a replica, and can be bought on any replica watch web site for $30 to $80, for an automatic mov't.,  21J, made in China.
Also, the sub-dials will not function on this watch. A Daytona needs the proper movement to operate the chronograph as it was intended..... To act as a stopwatch.. and measure time... seconds, minutes and hours. This is done by activating pushers at 2 and 4 positions, and the pushers on 21J replicas just don't operate a chron. for the purpose of measuring time. They may move and measure something else, like military time, or the date, but definitely not record seconds, minutes or hours. There are also no manuals on how to operate the Daytona that comes with these replica watches. You should know how this watch functions and how to operate the pushers, and what they do before you should buy and enjoy this type of chronograph watch. It's simple, just take the time to ask people in the know... how the daytona works, what the sub-dials measure and how to use them, etc. In no time you'll understand the operation of this beautifully made watch. Unfortunately, a daytona is out of reach for most of us... That's why seeking out a quality rolex replica for much less money is the way to go if you love this watch... A quality one can look, feel, and function just as good as the authentic Daytona, and you won't have to out out over $10K to get one.
