Hi forums,
I want to share and ask this forums.

Does anyone get the watch with “3 case reference” in one watch? (I see most coming with only “2 ref” such as 2852-2853 or 2846-2848)

My watch:
(it looks original one and correct to my eyes):


I think this combination can be found in “jumbo” (36.5 mm excluding crown) seamaster with “officially certified” that using caliber 354.

I search about the ref. 2657 that should be “sub-second” version
However, it should look like another reference such as “2846-2848” that can correctly use cal. 491(sub-second) or cal.501 (center-second).

Thanks @hoipolloi for always advice me.

Regards,
Teerapat
