Rolex 4131
ConfirmedVisible through the display back on the platinum reference and hidden on the rest, which means for most 126500LN examples the caliber must be inferred from the reference rather than observed. The 4130 and 4131 are close enough externally that this is one of the few current Rolex calibers an examiner cannot readily confirm at the bench.
