ROLEX YACHT MASTER BLUE

This looks like a Rolex Yacht-Master 40 — steel case with a blue dial, Oysterflex-style rubber strap, and the signature bidirectional rotatable bezel with a raised numeral scale. It’s shown on a display cushion in front of a box branded with a “Z” logo (looks like a watch dealer or reseller’s packaging).

A few things worth noting: given the “Z” branded background and the way it’s staged, this may be a replica or a listing from a reseller rather than an authenticated Rolex boutique piece — genuine Yacht-Masters typically aren’t marketed this way. If you’re looking to verify authenticity, I’d be happy to point out what to check (case back engravings, movement sounds, bezel action, etc.) — just let me know what you’re trying to figure out about it.
