Quick TakeThis Longines Master Chrono, oh man, it's a classic! That 42mm steel case houses a gorgeous barleycorn dial with those blued steel hands just popping! You can't miss the painted numerals! And check out that automatic L688 engine purring inside – 60 hours of go-go juice, plus the column wheel chronograph, ready to time anything. A real looker, this watch combines heritage with the capability of a true tool.

DescriptionThe L2.759.4.78.3 features a circular, stainless steel enclosure with a diameter of 42.00 mm and a thickness measuring 14.20 mm. The architecture integrates a 21 mm lug width, expanding to 49.50 mm lug-to-lug, contributing to its presence on the wrist and an overall mass of 102.6 g. A scratch-resistant sapphire crystal protects the dial surface, mirrored on the underside with a transparent case back of the same material showcasing the movement. This assembly is designed to endure water exposure to pressures equivalent to 3 bar.

The dial, presented in a silver "barleycorn" finish, is marked by painted Arabic numerals, contrasting against blued steel hands. Driven by the L688 caliber, the automatic movement provides standard timekeeping functions (hours, minutes, a subdial for seconds located at the 9 o'clock position, and date). This self-winding mechanism oscillates at 28,800 vibrations per hour, amassing a power reserve of up to 60 hours. The chronograph function is managed by a column wheel and provides readings via a central 60-second hand along with subsidiary dials indicating intervals of 30 minutes at 3 o'clock, and 12 hours, integrated into the lower section, at the 6 o'clock marker. The watch is delivered on a brown alligator strap and fastens via triple safety folding clasp, activated by push-piece.
