Few months back I bought silver hc for one of my
movements but none will seat in that case right
so I did research on and I found that the case is for model 1888 waltham
So to ebay for model 1888 I found lot of 3 from our own R.V.J(tymekeeper005) after a day of work I have one model
1888 done and ticking
few pictures of the project first set back was the balance wheel with some glue some bucher use glue to set the roller tabel in
my movement was not ticking so I made him tock

3 movements I pick one and went to work.

finish product all serial # are matching ther is serial # on the mainspring barrel as well

Nice work Peter, These '88 models are a nice movement.I can't understand why Waltham made these to fit an oddball case, there are many nice movements floating around, but no cases.I have a beautiful 15J 88 model Riverside movement, but like everyone else, no case.Maybe one will turn up someday.Good luck finding a case for yours !...Ted.

Thank you Theodore.
Illinois did same thing with Sangamo size 17 and
Hamilton did have early watch in size 17 or 16.5
Is waltham model 1872 also size 17?
as Im looking to buy one movement.

Peter the model 72 is a different size and not the same as standard 16s or model 88.

Thank you for the info and those 3 movements.

here is the case
