Hello,
I have a simple Waltham ORD. DEPT OF-xxxxxx with an unknown mark between the lugs "K-W-2". Anyone knows what it mean ?
tks,
Arend

Thank you for your posting Marcus, and welcome to NAWCC-IHC.

While I have not seen anything specific about it, it is my understanding that K-W-2 was a military inspectors mark.

Best regards,

Greg

Thank you !
I would like to show the pics:

I believe it stands for Keystone-Waltham-2nd case style. I've seen other similar markings on Walthams for example, K-W-1 and K-W-3. These have all been Keystone cases. I've also seen K-H-1 and K-H-2 on a few Hamiltons. I believe (it's been a while since I've been home so I'm going by memory here)that I have a NOS case at home that is marked K-E-3 and it is stamped on the inside of the caseback as an Elgin. Also the original paper envelope it came in says that it was for an Elgin wrist watch. Hope this helps.
