Quick TakeThis Longines Master Collection is a symphony of complications! The self-winding movement brings chronograph, moonphase, day, date, and month together – a truly complete calendar. It has an old-school charm with its blued-steel hands and barleycorn dial. The 40mm steel case feels balanced and contemporary, a daily-wearer with undeniable wrist-presence. It’s like having a tiny, precise observatory strapped to your wrist.

DescriptionThe L2.673.4.78.3 model features a circular stainless steel enclosure, measuring 40.00 mm across and 14.30 mm in height, with a lug-to-lug span of 46.70mm, and a 21mm inter-lug width. A transparent sapphire crystal constitutes the case back, complementing the scratch-resistant sapphire crystal protecting the dial. The assembly provides water resistance to a pressure of 3 bar and presents a total mass of 93.7g. A silver "barleycorn" patterned face contains painted Arabic numeral indices, paired alongside blued steel hands for legibility.

This timepiece utilizes the L687 caliber, a self-winding mechanical movement. The L687 operates at a frequency of 28,800 vibrations per hour and amasses a power reserve reaching 66 hours. Functionality encompasses standard hour, minute, and a subdial seconds display, integrated with a 24-hour indicator. Date is displayed with central half-moon hand. A moon phase indicator resides at the 6 o'clock position. The chronograph functions offer a sweep seconds, a 12-hour counter combined with the moonphase, and also has a 30-minute counter at the 12 o'clock location showing the day and month. It is equipped with a column-wheel operated chronograph.
