Oyster Datejust White Gold RX579 Ladies - faux

The simplest way to find out is to take it to a Rolex specialist repairer and ask them to look at it. They will know what small clues to look for to find out. Some of the clues could be inside the watch on the inside mechanism so a watch repairer will have the tools to open it correctly.

Farrah, Contact Seiko or try Google search your watch Seiko # and see what comes up then try the second #. Check the attached links,instruction and guides, Good luck

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.

Some movement noise is ok, however it may be time for a service - Take it to any Rolex re-seller that offers repair or to any good timepiece service center. If its a vintage piece i would recommend sending it to Rolex, paying the extra cost to receive the watch with full Rolex repair documents and service history. The Rolex web site has information on this. Also this company does a fine job on Rolex repair. https://www.bobswatches.com/rolex-repair-service

Hello. Go directly to the Rolex homepage http://www.rolex.com/en#/home/

That way you will know if the watch is still available new. If that doesn't help, go to ebay. J.

If I understand right, by the latch you mean bracelet clasp. You just pull it by the crown. Clasps on ROLEX watches can be very tight, so, have to pull it with appropriate force. Rate me, plz.

Best bet here is to go to a dealer that carries that brand and seeing if they can order you a new caseback.
Or, you can look for the same model online or EBAY that is broken or in disrepair, then just scrap it for the caseback. (It is not always possible to find one, but i recommend trying as this is the least expensive way to obtain small parts).

Here are a few links that may help:

Sometimes Rolex bracelet clasps are very tight and this only shows the quality of the watch.
Don't be afraid to pull the clasp hard enough to open it- nothing will brake as Rolex is designed for quite hard use.
If you can't do it by hand, try to use flat butter knife end as a lever.

Depending on how old the watch is, It may be quick set or older models are not quick set. In older models you need to unscrew the crown, pull out the crown and rotate the crown to set the time, and in order to set the date rotate the hour hand past 12 twice in order for the date to change. Set the date first and then set the hour and min. For quick set models unscrew the crown and pull it out to the fist click this position you can "quickly" set the date by rotating the crown. Set the date and then pull out the crown to the second position out. Rotate the crown to set the hour and min. Then push the crown back in and screw it down.
