Tag Heuer Crown and Tube replacement

Recommended Posts

Hello all,

Got this Tag Heuer Sel WG1210-KO from my friend, but the crown and tube were completely rusted.  Managed to pull out the crown and tube but they both need a replacement.  The tube was completely rusted, hence can't really take any measurement, may I know what is the right size of both crown and tube?  I found from Cousin UK, it seems the crown is 5.25mm diameter and 4mm depth, but not sure which tube size should I order.   Please help.

I did remove both Stem and tube, but as you said, the tube and crown thread was completely rusted hence couldn't measure its size.  Yes, the movement is ETA955.  I got a new stem already, but need to order a right size tube and crown.  Just don't know the size of the tube.

I'm checking on an SEL I have stripped here. The crown is 5.25 mm with what looks like either a 2.1 or 2.2 threaded inner tube, Cousins part number looks like C8612

For the tube, It's 2.6 OD and 7mm long. I can't be sure if it's ID is 2.1 or 2.2mm as that's the threaded part. I'm leaning towards 2.1mm so Cousins part number should be C8623. I would suggest you buy a 2.1 and 2.2 ID tube to be safe.

Thank you so much gbyleveldt for your advice and information.  I checked from Cousins, the ID2.2mm one says for Crown 5.5mm which I think may not be right for crown 5.25mm.  I think I will go for C8623 although its 6.9mm long which is for screw down crown as per Cousins.   Thanks you.

    • I don't have access to real-time or specific part numbers for Rolex watches. To obtain the accurate part number for the balance sock of a Rolex 1530, I recommend reaching out to an authorized Rolex service center or a qualified watchmaker. They will have the expertise and access to official Rolex parts databases to provide you with the correct information and assist you in finding the appropriate replacement part for your specific watch model. https://luxurysouq.com/product_brands/rolex-watches/
    • as far as I can tell for grand Seiko the only thing out there if you're lucky is the parts list. There appears to be no grand Seiko service manuals online at least that I've ever found. I do have a couple of links that talk about grand Seiko including the parts list.   https://mizeni.com/movements/seiko-5646 https://www.theseikoguy.com/grand-seiko-vintage/
    • Could you share the like from Amazon where you bought this? Thnx
    • Very informative thread! After reading through, I ordered a lamp from Amazon. Under $49 US (£39) tax shipping and delivered in 6 hours, yep! This one has 5 intensity levels and 5 color settings from 3200 to 6500. I use a binocular microscope and have the gooseneck lamp in case I need directional light. Don't mind the clutter of watches, those are usually moved off the bench when working on a watch. This really lights up the area nicely. The ring of leds on the binoculars is fairly cool when compared to the new lamp. I like it because once set it returns back to the setting when turned off and back on again.
