Rolex Silver Datewheel , a couple of questions,

[andypandy]

I am clearing out some of the bits and pieces from my spare-parts box.
I found this silver datewheel , which I originally bought to replace a Rolex
service dial. I believe this wheel is for a 1680-1655 and is not suitable for a 1675. Can anyone tell me exactly what it is , I tried researching it , but my feeble old brain can't cope with all the 'open 6's and open or or half open 9's ' you will have got my drift ? Is it worth selling or do I put it away again and let my son sort it all out after I've gone to join the ancestors ? I would appreciate any advice.

With reference to the above, it might help if I posted some pictures..... DOH !

I thought that the silver metal finish date wheel for the 1600, 1675, 1680, 1655 and 1665 were all interchangeable and the same as they all have the same bases caliber 16XX.

I'd be interested to know if I am wrong about this.

I did buy a silver date wheel some time ago for a 1675 and it worked perfectly when the watchmaker at first glance said it looked too small. The cyclops can be deceiving

Stavrodos , My old watch-smith told me that this wheel is not suitable for alkl 1675's.
Apparently , some of the wheels have curved or hooked teeth on the inside rim, they are suitable , but the centre positioned ones , like mine , seem to display the date slightly lower . Over to the wheel experts.
