Hi all,

Trying to ID this one:

• Dial: Signed HEUER, shield logo. Luminous Arabic 12/6, drop markers elsewhere. Two registers (running seconds, 30-min). Telemeter + tachymeter scales. Cushion case, faceted lugs, 3 pump pushers/crown.

• Movement: Landeron cal. 248.

• Inside caseback: stamped “3876”

• Outside caseback: “MADE STAINLESS STEEL GUARANTEED 5ATM 165 FEET,” code “AF03,” and “2191 H” / “B” below, plus a decorative mermaid/water-nymph engraving. No “Heuer” text on the caseback itself.

Can’t match “3876” or “2191 H B” to anything in the OnTheDash Master Reference, and the caseback style (generic engraving + alphanumeric code, no brand name) looks like a generic Swiss case-maker’s case rather than a proprietary Heuer one.

Anyone recognize these codes, or know if this is a documented Heuer/Landeron 248 combo that’s just missing from OnTheDash — or does this look like a period re-case (genuine Heuer dial, non-Heuer case)? I am also interested on the price value of the watch.

Photos attached (dial , movement , both caseback sides ). Thanks!
