This ref. E335 is an early Lecoultre chronograph made largely for the US market with column-wheel Valjoux 72. The dial and movement are marked as Lecoultre-only for trademark & import tax reasons. This was standard practice for the brand from 1937 until 1985, with a few exceptions. This examples sports a white-silver dial, blued steel hands, applied steel numerals, tritium, 36mm steel case, and sharp angular lugs. This is in every detail a peer of the Carrera or Pre-Daytona crowd, but was simply not as widely sold.
