Important details

This Master Collection edition is distinguished by the black dial with fine decorative texture and contrasting silver Roman numerals.

The chronograph is clearly laid out with two counters:
– 30-minute counter at 9 o’clock
– small seconds at 3 o’clock

At 6 o’clock there is a separately framed date window.

The polished case, classic Roman numerals, and feuille-shaped hands give the watch a strong traditional Longines appearance, while the chronograph function adds a sportier character.

Year of construction

Estimated year of construction: circa the second half of the 2000s to the early 2010s.

Reference L2.669.4 belongs to an earlier generation of the Longines Master Collection. Without dated papers or additional serial documentation, an exact production year cannot be determined.

Case

The round case is made of stainless steel and measures 38.5 mm in diameter.

The case is predominantly high-gloss polished and features the characteristic rounded form of the Master Collection. On the right side are the crown and two rounded chronograph pushers.

The relatively classic diameter of 38.5 mm makes this model noticeably more understated on the wrist than many modern chronographs.

The case shows light signs of wear and fine scratches consistent with normal use. The overall presentation is well kept, with no obvious heavy damage.

──────────────────

Dial

The black dial features a fine guilloché/texture finish that becomes clearly visible depending on the light.

Time is displayed with large silver Roman numerals and polished feuille-shaped hour and minute hands.

Around the outer edge there is a precise minute scale with Arabic five-minute markings.

The two recessed sub-dials have a fine concentric finish and contrasting white scales.

Below 12 o’clock is the Longines inscription and the winged hourglass logo. Above 6 o’clock is “AUTOMATIC.”

The rectangular date window is located at 6 o’clock.

The dial presents very neatly and the various inscriptions and scales are sharp and easy to read.

──────────────────

Chronograph

The watch features a mechanical chronograph function.

The upper pusher starts and stops the chronograph. The lower pusher resets the chronograph hands.

Elapsed seconds are indicated by the central chronograph hand, while the 9 o’clock sub-dial records up to 30 elapsed minutes.

The 3 o’clock sub-dial is dedicated to the running seconds of the movement.

Movement

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

Caliber: Longines L651.3
Basis: ETA/Valjoux 2894-2 family
Winding: automatic
Frequency: 28,800 A/h
Number of jewels: 37
Power reserve: approx. 42 hours

The movement features decorative finishing and a Longines-signed rotor and is visible through the transparent case back.

Timegrapher measurement

During the measurement the watch displayed the following values:
Rate: +15 seconds per day
Amplitude: 341°
Beat error: 0.0 ms
Lift angle: 52.0°
Frequency: 28,800 A/h

The measured beat error is very low. The amplitude is relatively high and the measured rate is about +15 seconds per day.

A timegrapher measurement is always a momentary snapshot in a single position and does not guarantee daily wrist variance or the future mechanical state of the movement. If a more precise daily rate is desired, regulation can be considered.

──────────────────

Crown and pushers

The knurled crown is Longines-signed and is flanked on both sides by the two rounded chronograph pushers.

The combination of the large crown and classic pushers fits well with the traditional design of the Master Collection.

──────────────────

Case back

The watch has a transparent case back, allowing the automatic movement to be seen.
Around the glass back are the markings “THE LONGINES MASTER COLLECTION”, “ALL STAINLESS STEEL” and “SWISS MADE.”
Through the glass the decorated movement with Longines-signed rotor and caliber designation L651.3 is visible.
The polished steel rim of the back shows normal light signs of wear and fine scratches.

──────────────────

Strap

The watch is fitted with a black Longines crocodile leather strap.
On the inner side are the Longines marking, size 20 and the designation “ALLIGATOR LEATHER.”
The strap has a classic black crocodile/alligator texture and black stitching. There are clear signs of use, mainly around the punched holes, folding zones, and on the inner side. The strap is still usable but shows worn character.
The mounted steel folding clasp is Longines-signed and shows light signs of wear.
The current combination is suitable for a wrist circumference of approximately 19–20 cm, depending on the desired wear comfort.

Water resistance

This type of Master Collection originally came with a limited water resistance of about 3 bar / 30 meters.
With a used mechanical watch, the original water resistance cannot be guaranteed without a recent pressure test. A pressure test is recommended before exposing the watch to water.

Overall condition

A well-kept example of the Longines Master Collection L2.669.4 in the classic 38.5 mm edition. The combination of the black textured dial, Roman numerals, double chronograph counters, and black Longines crocodile leather strap gives the watch an elegant and traditional appearance.

The watch shows normal signs of use, with the leather strap notably worn. The case, dial and glass present themselves overall neatly. The automatic Longines L651.3 movement is visible through the transparent case back and was measured by the timegrapher at approximately +15 seconds per day.
