Got a great deal on the timepiece but first owner had the crown replaced. Would love to bring it back to original spec. Any ideas where to look?

 

Um ... authorized dealer? But seriously, just wait until it is time for a full service and have it done by the service center. They will replace the crown.

 

Finding one the right size will be the challenge - I measured it as 6.7mm diameter x 2.3mm depth (no idea of the thread size) and can't find that size on any regular online dealers (Cousins, Ofrei etc).

... but I'm with Dan S above; if you take it into a Tag Heuer boutique then I'm sure you'll be able to get them to replace it. Given that the CS3111 is quite likely 20 years old now, maybe it's due a service anyway

I was playing with mine the other night, trying to figure out which combo of strap vs Abel Court BoR works best...
