Hello! Awhile back I bought a beautiful 1958 vintage piece from EFauser. I love this watch and it gets worn quite often. Unfortunately, the leather strap has began to tear, so its time to replace it. Unfortunately, I don't know what size I need! I thought it was a CK 2849 with a Caliber #503. But looking at the photos, I am not sure I am right! Can anyone help me identify this watch so I can get the correct strap! I'm looking for a brown leather!
