Hamilton 950E Model 3 – Rare 23 Jewel Railroad Chronometer

This exceptional Hamilton 950E represents the pinnacle of American railroad‑grade watchmaking—a true ultra‑high‑end timepiece prized by serious collectors. Powered by Serial #2631256 and designated Model 3, this example dates to circa 1939, placing it near the end of Hamilton’s elite 950E production run.

Fresh from a recent service, the movement runs with the smooth, effortless precision expected from Hamilton’s finest 23‑jewel engineering. The plates remain remarkably clean, showing no signs of wear, abuse, or mishandling—an uncommon level of preservation for a working railroad watch.

The watch is housed in its original Hamilton‑marked 10k gold‑filled Keystone “Boss Style” case, a premium and highly desirable pairing that complements the movement perfectly. Its double‑sunk dial features the bold boxcar numeral motif, paired with classic baton hands for a crisp, authoritative railroad aesthetic. A couple of honest age marks are present: a small scuff near the edge above the 8‑hour marker and a faint hairline near 12. The seconds hand differs subtly from the main hands—an elegant detail that requires close inspection to notice.

Examples of the 950E in this level of originality and condition are increasingly scarce. As one of Hamilton’s most sought‑after railroad grades, it represents a rare opportunity to acquire a top‑tier piece of American horological history.
