Vintage NOS New-Old-Stock Pocket Watch Glass Crystal – price is per piece (not for entire lot lol). I have just finished sorting over 30,000 NOS glass crystals from a HUGE watchmaker’s estate and a watch materials distributor!! Everything is sorted, but so far, I only have some listed. Please, please, please ask me for other sizes! I have as small as 4-ligne up to 22-ligne! Most of the larger are the typical concave and mi-concave, but I do have some flat parallel. I have a great mix of hunting case wafer-thin sizes throughout as well as open face for smaller sizes. These are primarily VTF with some W.B. & Cie and maybe others. An absolutely HUGE ASSORTMENT OF SIZES! Check the drop-down list, but please, please, please ASK ME FOR MORE! Ask for the proper size, measure twice or thrice and order once! Let me know the size you’re looking for! I don’t care if it’s listed or not, I’ll look for it!! I want to help you and I both get it right the first time! If you need any other sizes, please let me know! I have everything from the 4 (ligne) size up to 22 (ligne) size. For reference, I like to use a chart provided by pocket-watch-database dot com, but I will be glad to look and search my complete stock to help you obtain a clean finish on your old project watch! Please note, there may be some variation within the listed size, IE: height, thickness, domed, etc. If you do not contact me, I may contact you right away in an effort to ensure you receive what you are expecting. These old systems weren’t always consistently ideal to work with! Pictures are just a small sample, but yes, there are 3-packs and even 5-packs of new-old-stock wrapped goods!! S&H via USPS 1st Class includes tracking only. Priority Mail is available if you want to upgrade! Will gladly combine shipping on these and more than happy to work a package deal!! **PLEASE NOTE: I reserve the right to cancel if I find that an item is chipped or damaged! While I have tried my best to inspect all these pieces, it is near impossible. I will contact you if that situation arises, but let’s work together, buyer and seller, to have a quick, easy and successful transaction! Due to the age/nature of these old glass pieces, I may opt to notify if a crystal is simply not in sellable condition. THANK YOU! Sample lot available, other lots made to order.
