: Hi Steven,

: Beautiful piece you have there! What you’ve got is a classic
: mid-century Heuer chronograph, most likely from the late 1940s
: or early 1950s.

: To answer your question about the model name: back in this era,
: Heuer didn’t use commercial names like Carrera or Autavia
: (those only started in the 1960s). In the collector community,
: this entire generation is affectionately known as
: "Pre-Carrera" chronographs. Instead of names, they
: were identified solely by reference numbers.

: Based on the steel case with straight lugs, the round pushers, and
: that gorgeous "bi-compax" dial layout with Arabic
: numerals, it is highly likely to be a Ref. 2403 (often powered
: by a Landeron movement) or a variation of the Ref. 346 / Ref.
: 2443 family (usually housing a Valjoux movement).

: By the way, buying it at Grand Central Terminal 30 years ago makes
: perfect sense—likely from the iconic Central Watch shop inside
: the station, which has been a staple for vintage timepieces in
: NYC for decades!

: If you ever have the strap removed, check between the lugs at 12 or
: 6 o'clock; you might find the 4-digit reference number engraved
: there, which would confirm the exact model.

: Wear it in good health!

Hi Paulo,

Thank you so much for your amazing response and details. Great to finally know the model and I will check the reference number as soon as possible. Again, thank you so much for your help.
All the best
