I just bought some 3rd part springs off of amazon for about $20 for 3 or 4.It just snaps back into place. Bezel is on there quite secure with the new spring. The detents just aren't as distinct as before.
The ratcheting seems to be more a function of the little wire spring.I bonked my watch on my desk and this happened.The spring was nowhere to be found.I replaced the spring and there was noticeable less ratcheting than before.
There's a navy shell Camberly GMTO in process right now.And the Cavendish was available as a stock model in navy shell fairly recently.http://webcache.googleusercontent.com/search?q=cache:4g5EtA0Ee4MJ:www.crockettandjones.com/fr-fr/product/cavendish-navy-cordovan+&cd=9&hl=en&ct=clnk&gl=us
