Important details
──────────────────

This edition stands out for its classically designed silver-colored dial with a fine, repeating guilloché pattern.

The large black Arabic hour numerals contrast strongly with the light background. The black feuille-shaped hour and minute hands complement this nicely.

The chronograph is deliberately executed symmetrically with only two subdials. This keeps the dial calm and legible despite the chronograph function.

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

At 3 o’clock is the small seconds for the normal time display.

The date is separately positioned at 6 o’clock.

──────────────────
Case
──────────────────

The round case is made of stainless steel and has a diameter of 38.5 mm.

The case is predominantly high-gloss polished, which suits the formal character of the Master Collection well. The curved lugs lead elegantly toward the leather strap.

On the right side are the crown and two round chronograph pushers. The upper pusher starts and stops the chronograph; the lower is used for resetting.

The case shows minor signs of wear and fine surface scratches, mainly on the polished parts. No obvious heavy damage is visible.

──────────────────
Dial
──────────────────

The silver-colored dial is one of the key features of this edition.

Finish: fine guilloché pattern
Hour markers: large black Arabic numerals
Hour hand: black feuille hand
Minute hand: black feuille hand
Chronograph second hand: central long hand
Minute scale: fine scale around the outer edge
Logo: Longines with the winged hourglass below 12 o’clock
Inscription: AUTOMATIC above 6 o’clock
Country of origin: SWISS MADE at the bottom

The two recessed subdials have a fine concentric finish, subtly distinguishing them from the guilloché pattern of the central portion.

The dial is in very nice condition and the crystal also looks clear.

──────────────────

──────────────────

The watch features a mechanical automatic chronograph function.

Central chronograph second hand: yes
30-minute counter: at 9 o’clock

The central chronograph hand can be used to measure elapsed time, while the 9 o’clock counter records elapsed minutes.

──────────────────
Date
──────────────────

At 6 o’clock there is a separate rectangular date window.

The bottom placement preserves symmetry between the two subdials and ensures the date function remains clearly legible.

The Master Collection features a transparent case back, allowing the automatic movement to be visible.

The rotor bears the gold-coloured Longines signature and the caliber designation L651.3.

Around the viewing window are the usual Longines engravings of the Master Collection, including the collection designation, material and water resistance information.

The back shows light superficial signs of wear appropriate for normal wear.

The ribbed crown is signed with the Longines logo.

Above and below the crown are two round, polished chronograph pushers. These classic round pushers suit the traditional design of the model.

──────────────────
Bracelet
──────────────────

The watch is equipped with a dark Longines leather band with crocodile structure and light contrasting stitching.

The inside is marked with Longines markings and the designation “Genuine Leather.”

The band shows clear signs of wear, especially around the used holes and the parts where the leather bends during wear. The stitching is also visibly worn.

──────────────────
Clasp

The band features a signed Longines folding clasp.

The polished upper side bears the Longines name and the winged hourglass. The clasp shows light superficial signs of wear.
