This one has me stumped on model ID. I can find similarities in others, but nothing exact. I can't find one with these exact lugs that doesn't have engraving. I'm thinking it might have a replacement movement because it is stamped "L2" and the case is stamped "L1". There are no servicing scribes inside the case back. The bezel is 10k RGP and the back is stainless. Anyone know what this is?
