Case Clamp for Seamaster Case 6546

[AndrewG]

All,

I have a 14k 1958 seamaster with the case reference GX6546. It needs a new case clamp- does anyone know what omega part number suits it? The movement is a cal 500. I've search Otto Frei and the case reference does not come up.

The case reference has been on sale in a couple websites, so not that rare. I figure there must be some compatibility with another case clamp from another case.

Thanks for any help!

Can't really help. Didn't find anything in my bestfit book, but I really bought it for crown matching

Jules Borel lists 3 based of the caliber 470

Prices probably not up to date

If two clamps. Remove the second and measure

CLAMP, CASE 2.0X2.4 BENT 1911/OME 470 $16.10
CLAMP, CASE 2.0X3.3 BENT 1974A/OME 470 $4.10
CLAMP, CASE 2.0X4.0 BENT 1974B/OME 470 $4.10

Don- thanks, this resource is very helpful.

I did actually just remove the other clamp and it measures approximately 2mm long by 1.8mm wide (that width is sliding into the calibre 500, so I assume that is standard, the 2mm long is the length engagement the case groove).

The clamp is indeed bent at the case side.

Don- thanks again. I've chased through all the alternative cases in this class and they all use the same clamp- 2.0x2.4 (which may include the total length and bend that I am not measuring). I can review the case references on line and see they are the same as mine.

Again, many, many thanks and happy friday 😀
