See images for further details. Note someone has also indicated these are PUW 1363 compatible which I  have not yet been able to verify. These originally came packaged as 1\/4 doz but there are only two in the envelope.  I specialize in hard to find parts so I'll usually have whatever you might need and all watch parts are unconditionally guaranteed. Images do an adequate job of representing the item.\u003c\/p\u003e","brand":"Bestfit","offers":[{"title":"Default Title","offer_id":49099150033204,"sku":"SJW-BE1002376BS-04","price":6.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0849\/3341\/1124\/files\/2026-04-1612.58.41.jpg?v=1776369762","url":"https:\/\/www.vintagetimeparts.com\/products\/bestfit-balance-staffs-2-for-standard-caliber-191-movements-new","provider":"Vintage Time Parts","version":"1.0","type":"link"}
