When working on watches you will find many sizes of seals and this will keep me from always waiting for another to arrive.

The options fit well and no water got in through the crown. Can't ask for more.

THERE IS A GOOD ASSORTMENT OF O-RINGS IN THIS PARTICULAR PRODUCT. OTHER PRODUCTS LIKE THESE SKIP HALF SIZES, WHICH BECOMES ABSOLUTELY NECESSARY WHEN DEALING WITH SUCH SMALL PRECISION OPENINGS( WATCH TUBES). THE EXTREMELY FRUSTRATING THING IS THE CONTAINER. I RECEIVED THE O-RING ALL MIXED UP!!! SO ALL THE SIZE LABELING AND COMPARTMENTS BECOME USELESS. EACH SIZE NEEDS TO PUT IN SMALL PLASTIC BAGS THEN PLACED IN THE APPROPRIATE COMPARTMENT OR SOMETHING TO THIS EFFECT.
