Reference L2.631.4 belongs to the earlier generation of the Longines Master Collection. Exemplars of this reference have been documented around the mid-2000s and the model remained in production for several years thereafter. An exact individual production year cannot be determined without accompanying dated documentation. ────────────────── Case The round case is made of stainless steel and has a diameter of 38.5 mm excluding the crown. The case is largely high-gloss polished and features the classic long, lightly curved lugs that are characteristic of this generation of the Master Collection. The polished surfaces show light hairlines and normal superficial signs of wear. The overall presentation of the case is well-kept and there are no noticeable heavy damages or large dents. ────────────────── Dial The silver-colored dial has a very fine, repeating guilloché pattern that provides a lot of depth. Time is displayed with large black Arabic numerals. The classic typography corresponds to the traditional design of the Master Collection. Below 12 o’clock: LONGINES winged hourglass logo Above 6 o’clock: AUTOMATIC GMT At the bottom: SWISS MADE. The actual time display is surrounded by a detailed minute and second scale. The dial is in very neat condition. ────────────────── Hands The watch is equipped with classic blued steel feuille hands for hours and minutes. Depending on the light, these visually range from almost black to bright blue, which nicely contrasts with the light guilloché dial. Additionally there is a slender central second hand. ────────────────── GMT and world time function The special element of this version is the combination of GMT and world time indication. Around the central dial there is a 24-hour ring with the numbers 1 to 24. Around it lies a broad ring with place names representing different international time zones. Included are, among others: London Paris Cairo Riyadh Dubai Karachi Moscow Dacca Bangkok Beijing Hong Kong Tokyo Sydney Noumea Auckland Samoa Hawaii Anchorage Los Angeles Denver Mexico New York Santiago de Chile Rio de Janeiro Azores Through the combination of the 24-hour indication and the cities ring, the watch can be used to read off different international time zones. This makes the L2.631.4 one of the more distinctive travel complications within the classic Master Collection. ────────────────── Date At 3 o’clock there is a clearly framed date window. The date is displayed with black numerals on a light background. ────────────────── Movement The watch is powered by the automatic Longines caliber L635.6.

Around the sapphire crystal are, among other things, the characteristic Master Collection markings engraved. The polished metal rim shows light superficial signs of wear consistent with normal use. ────────────────── Crown The knurled crown carries the Longines inscription and the winged hourglass logo.

The combination of the silver guilloché dial, black Arabic numerals, blued feuille hands, date, 24-hour ring and extensive world cities ring gives this model a distinctly recognizable look. The case and clasp show light signs of use, while the dial, in particular, presents very neatly. The dark brown Longines leather strap is clearly worn but, in terms of color and the classic crocodile texture, is a fitting match for the watch. The automatic L635.6 movement remains visible through the transparent case back.
