Bestfit 2-piece stem / winding arbor #340/9 for AS caliber 1200, 1202 Waterproof Watches

ONE Bestfit 2-piece FEMALE stem for AS caliber 1200, 1202 and liklely 1187 movements, from the Bestfit Assortment #340 of waterproof stems, No. 9, new in envelope.  See images for further details. Fitting stems without the original is as much of an art as it is a science, especially with waterproof stems, as setting the correct stem length is critical to the crown achieving a good waterproof seal. I specialize in hard to find watch parts and all watch parts are unconditionally guaranteed. If you need a part for an American watch I likely have it. Images do a pretty good job of representing the item.
