I recently purchased a 1920s Cartier Tank in White Gold and was hoping to find some guidance from this community on replacing the strap/buckle with something more period correct. I was thinking a deployant buckle from the period would have a white gold exterior with rose gold interior clasp and non-adjustable strap length. Does anyone have an insight on where I could find such a deployant buckle/clasp? The current strap on the watch is 16mm and am told a 16mm or 14mm clasp could work with this piece.
Separately, I've long admired a metal mesh bracelet for this type of watch and would also have an interest in a piece like the one in the picture attached.
