Hello everyone and good day! Just wanted to share an almost uncommon, interesting and beautiful Hampden movement with you. This is the grade 220. It is 6 size, 17 jewels and adjusted. As far as I can tell it's also Hampdens top of the line 6 size movement. The chapter 149 database estimates 2,650 total movements. A little while ago I picked out some 6 and 12 size movements I would like to find, and this is one of them. This is 826050. Estimated around 1891. The Hampden blue book first has one recorded at 540534, so they first came out a few years earlier. On page 63 of the Hampden Blue book there's a great description. "Nickel, 17 fine Ruby jewels, Raised gold center and train settings, highly polished center and escape wheels, Gilt and nickel damaskeened, the Hampden back action mainspring, finest grade hair spring, Gilt beveled screws throughout, fine Gilt spade hands, glass enamel or fancy dial, adjusted to 5 positions and very accurately timed, the best 6 size watch on the market" Now looking at my movement, this all holds true. I would love if it had the fancy dial, but this one has an Arabic glass dial with red 5 min markers. It does have Gilt spade hands. The finest 6 size watch on the market... Well I'm sure that's an argument that could continue for years around here! I will say that the two tone is not as brilliant and sharp as some Waltham or Elgin movements I've seen. This case is not original. I was able to get this as a movement only. I feel like I did a respectable job of finding a suitable case. This is a Wadsworth, gold filled case with high relief and raised stars. It held a wrecked 15 jewel Hampden close in age.. so it fits very well. It's about the size of a 12s watch and it's just gorgeous. Really a top quality gold filled case. Yes the crystal is missing... I'm about fed up with hunter case crystals at the moment so it will get one down the road. The lid does open farther than it should, but with the quality of the rest of the case it's not a big deal to me at all. The whole thing is just hard to photograph. I can not get the right light so I hope I did an ok job showing the nicer features of the movement. It's not a perfect example, but I certainly like it quite allot. Here's another thread with a few of these movements shown. New Hampden Discovery Also included is a catalog page from the informational pocket watch threads sticky containing the grade 220. https://mb.nawcc.org/attachments/1896_a_c_becken_cat_pg_04_hampden_6s_-_400-size_lr-jpg.460578/ Anyone else have one to share? I'm sure some members here have ones much nicer than mine! What is a Hampden back action mainspring? I've seen these referenced a few times now and I just can find what it is. Questions, comments, criticism, watch pictures, anything welcome!
