CITIZEN BL5290-59F E812-S043646

Hello Ladies and Gents,

I've had this Citizen for over 6 years and it really needs some love. Ive been lucky enough to find another used one just like it so I now have spare links, case and internals if ever needed. However,  I cannot seem to locate the red bezel and I'm not sure where what to do about the crystal. Currently it is a mineral glass with some heavy scratching. Id like to replace it with a sapphire crystal maybe with a blue or red AR coating.

The model info is below. How can I locate the bezel and sapphire? Also is it just a better idea to send it for servicing to CITIZEN repair shop ? Thank you!!!

Hello, the best web sites that I have found to search watch parts like bezels (ceramic, steel and titanium) and sapphire cristal are Aliexpress and Ebay (you just must find same diameters and thickness in the case of sapphire glass) of course they only have compatible parts, not OEM parts.

But you cristal may be restored by using cerium oxide and patience.

Thank you for this. Is there anyway to figure out the dimensions from a blueprint or something? Or should I buy a digital ruler thing? Maybe I can take apart the spare I have just purchased.

Usually if you'd like it restored to looking like new sending it back to the factory or one other authorized service people is the preferred choice. That's because they should have access to all of the original components providing the watch isn't too old. It may be if you have someone authorized in your area you can ask them nicely and no giving the part numbers for the crystal and whatever else you need and then you can try to put them in yourself.

Blueprints yes the blueprints they exist but were never going to see them. They don't give us blueprints if were lucky we get a service bulletin or something. Like your movement I've attached the service manual. But that's it no detailed blueprints they probably don't want people remanufacturing their watch and were supposed to be just repairing them not modifying them anyway.

Sometimes on some of the watch parts there will be numbers and you can figure out like diameter of gaskets are crystals perhaps it just depends on the watch company.

I just did it with an analog caliber or a transparent ruler (cheap option for newbies), of course the best option is a digital caliber to get real dimensions.
