Stainless steel, wind up, still working.
Never used, this mechanical watch, no longer just a man's watch, is kept for safe-keeping in the vault, where the weather is just fine. Although, to attest to the quality, it still works after the past 30 years in my father's basement. It is yet another find from my his gift shop, left over after he closed up many few years ago. Let us know if you're interested.
