Description
The Longines Master Collection is a classic automatic for the wearer who wants a full calendar and chronograph in one dressy, 42mm package. The sunray blue dial and polished stainless steel give it a formal look that still reads well day to day.
Power comes from the automatic L687 movement, housed in a stainless steel case with a sapphire crystal and a transparent sapphire case back. The 24 hour indicator sits at 9 o'clock, the small seconds is integrated, and the date is shown by a half moon central hand.
The standout feature is the combined display: a central 60 second chronograph hand, a 30 minute counter, day and month at 12 o'clock and a moon phase at 6 o'clock. The stainless steel bracelet closes with a triple safety folding clasp and push-piece opening.
Frequently Asked Questions
Will the Longines Master Collection fit a 7 inch wrist?
With a 42mm round case and 21mm lug width, this Longines sits comfortably on most wrists from about 6.5 to 8 inches. The 14.2mm thickness makes it fairly tall, so check it against your shirt cuffs before wearing it daily.
Which movement drives it and how do I wind it?
It uses the automatic L687 movement, so it winds from wrist motion. If it has been off the wrist for a few days, give the crown a few turns to restart it. It also drives the chronograph and moon phase displays.
Can I wear it for swimming or in the shower?
This model has no water resistance rating in its listed specifications, so it is best kept away from swimming and showers. For daily wear, office use and light weather, it is a suitable dress watch.
How is it different from a simple automatic dress watch?
Compared with a plain three hander, it adds a chronograph, a 24 hour indicator, small seconds, day, month and moon phase. The alternative is a simpler automatic with better legibility and a slimmer case.
Can I swap the bracelet for a leather strap?
The steel bracelet has a 21mm lug width, so many 21mm straps can fit. Fitting is often easier with a spring bar tool, and the triple safety folding clasp stays with the original bracelet.
How often should this watch be serviced?
Mechanical watches like this one are generally serviced every 5 to 8 years, depending on use. A service center will check lubrication, the chronograph and moon phase mechanism, and the case seals.
Editor's take
The Longines Master Collection speaks to the buyer who wants a traditional complicated dress watch without moving into haute horlogerie pricing. It combines a full calendar, moon phase and chronograph, a recipe that Longines has built its reputation on for decades.
The heart of it is the L687 automatic movement, which drives a chronograph with a central 60 second hand and a 30 minute counter, plus a moon phase at 6 o'clock. The sapphire crystal and the transparent sapphire case back let you see the work and resist scratches in daily wear.
The trade-off is the density of the dial. With a 24 hour indicator, small seconds, day, month, moon phase and counters, the layout is busy, and quick legibility suffers compared with a simple three hander. The 14.2mm case thickness also means it can catch a tight cuff.
It suits someone who enjoys reading a complicated dial and wants a triple safety folding clasp on a steel bracelet. If you prefer a slimmer, simpler profile, a plain automatic dress watch in the same price bracket is the alternative to consider.
