It should be mentioned that there can be very small variations in all dimensions I have supplied-owing to the limitations of production methods at the time of manufacture.Experience shows that some Jewels fit better in some screws that in others and through fear of a poor fit I WILL NOT SUPPLY JEWELS ALONE.

ALL jewels supplied will unscrew from the screws-they are NOT glued together !

Owing to a recent misunderstanding, I confirm the listing is for ONE JEWEL & SCREW ONLY, CLIPS ARE NOT INCLUDED.

NOTE THE ORIGINAL 51 Jewels & Screws are now OUT OF STOCK. No questions please, I do not know when/if I will be able to restock/relist.
