Got this coming in. My first Sea-Gull branded watch. It's the M172s retrograde with sapphire dial, sapphire display case, 5ATM, black leather strap with butterfly deployment, stainless steel case, ST2505 automatic movement with power reserve indicator and rotating balance wheel. A bit of a poor man's tourbillon.
