Year of manufacture

Estimated year of manufacture: circa late 2000s to early 2010s.

──────────────────
Case

The round case is made of stainless steel and has a diameter of 40 mm. The predominantly polished finish gives the watch the classic look characteristic of the Master Collection.

The case has slim, curved lugs and a relatively narrow polished bezel, so the dial occupies a large part of the front.

On the right side are the crown and two chronograph pushers. The case shows light to normal signs of wear and fine hairlines appropriate for a worn watch. There are no noticeable heavy damages.

──────────────────
Dial

The silver-colored dial features a fine guilloché pattern and is one of the most recognizable elements of this variant.

Time is indicated with large black Arabic numerals and characteristic blued feuille hands. Depending on the light, the color of the hands shifts from nearly black to bright blue.

Along the outer edge is a detailed minute scale.

The chronograph is implemented with two recessed subdials with concentric finishing:

At 3 o'clock is the small seconds.

At 9 o'clock is the 30-minute chronograph counter.

The central thin hand is used for the chronograph seconds.

At 6 o'clock is the framed date window. The combination of guilloché, Arabic numerals and blued hands gives this edition a pronounced classic look.

The dial is in nice condition and shows no noticeable damage.

──────────────────
Chronograph

The watch features a mechanical chronograph function.

The top pusher starts and stops the chronograph, while the bottom pusher resets the chronograph to zero after stopping.

Elapsed seconds are displayed centrally and elapsed minutes via the 9 o'clock counter.

──────────────────

The watch is powered by the automatic Longines caliber L651.3.

Crown and pushers

The ridged crown features the Longines winged hourglass logo.
Above and below the crown are the two polished chronograph pushers. The combination is nicely integrated into the classic case design.

──────────────────
Case back

The Master Collection features a transparent case back, keeping the automatic movement visible while worn.
Around the viewing window are, among other things, the markings “MASTER COLLECTION”, “SWISS MADE”, “ALL STAINLESS STEEL” and the water resistance indication.
The steel back shows light signs of wear and hairlines.

The mounted combination is suitable for a wrist circumference of approximately 20 cm, depending on the chosen setting.
