67544 serial number on back of watch

go google and type in-- genuine rolex watch serial numbers -- search all the sites and check your numbers

That number does correspond with a genuine Rolex. Stop Ina watch repair store where they actually do the work. I have not seen a knock off with a serial numbers or model number stamped between the case lugs.
Hope this helps.

For Casio watches, the number on the back is the module number. For ROLEX I have no idea. Never saw one in my life.

Actually the information from Ironfist109 is incorrect. Rolex has the serial number between the lugs at the six o'clock position. The number between the lugs at the 12 o'clock position is the caliber number. Shouldn't be anything on the caseback, very rare with Rolex. Often is a good indicator it may be fake actually!

This model Rolex has been manufactured over multiple years, and it is not possible to date your watch based purely on is model number. However, it is possible to date most Rolexes based on their serial numbers, which can be found stamped between the lower lugs (i.e., the lugs below 6:00 on the watch dial). You will need to remove the band from these lugs to read the serial number.

Dating the watch case of a Rolex does not necessarily date the entire watch. It is possible that a movement from another watch was placed into a watch case that is younger or older than the the movement. Like Rolex watch cases, Rolex movements can also be dated by their serial numbers, if this is a concern you have about this particular watch.

This jeweler has put together a nice summary of when Rolex watch models were introduced and which serial numbers are associated with specific years of manufacture. Once you have found your serial number, this should help you date your watch. I have no connection (financial or otherwise) with this web site, but I found the information useful and presented in an easy to understand way.

Howdy..

Not sure what your question is.. but I assume you wish to know if you have the real thing or not.
The watch you describe is a reproduction and not the genuine article.

I am sure there are other indicators.. however the Daytona and 99.9999% of all Rolex watches do not have engraving on the back cover.
Best of luck

mcdevito75 here, Visit a small watch repair shop in your area, They"ll need to look at the movement for the numbers that count when I-D ing a watch, you can also refer to any numbers on the face or back cover of your watch. Rolex maintains good value also.
