Case

The round case is made of stainless steel and has a diameter of 38.5 mm. The highly polished finish, rounded bezel and elegantly shaped lugs give the watch the classic look characteristic of the Master Collection.

The case is in neat used condition. The polished surfaces show light hairlines and superficial signs of wear. There are no noticeable heavy dents or damage.

Because of the relatively modest diameter and the classic proportions, the model wears elegantly and understatedly.

──────────────────

Dial

An important feature of this execution is the silver-colored dial with the fine barleycorn or grain-like pattern. The repeating texture provides a subtle relief effect depending on the angle of light.

The dial features large black Arabic numerals and a detailed minute scale along the outer edge. On this outer scale, the minutes are indicated in five-minute increments.

Below 12 o'clock are the LONGINES inscription and the winged hourglass logo.

Above 6 o'clock is AUTOMATIC.

At the bottom of the dial is SWISS MADE.

The dial is in very neat condition.

──────────────────

Hands

The watch is equipped with the characteristic blued feuille- or leaf-shaped hands from Longines.

The blue finish contrasts strongly with the silver dial and can vary from very dark blue to bright steel blue depending on the light.

Additionally, the watch has a slim central seconds hand.

──────────────────

Date

At 6 o'clock there is a separate date window.

The date is displayed with black numerals on a light background and is neatly integrated between the Arabic hour markers. The watch shows the date as 20.

──────────────────

Movement

The watch is powered by the automatic Longines caliber L619.2.

Caliber: Longines L619.2
Type: mechanical automatic
Number of jewels: 21
Frequency: 28,800 A/h
Power reserve: approx. 42 hours
Functions: hours, minutes, central second and date

The automatic movement is wound by the rotor when worn.
Through the transparent case back, the movement and rotor are visible. The rotor features decoration and gold-colored LONGINES and L619.2 markings.

Timegrapher measurement

During the performed measurement, the following values were recorded:

Rate deviation: -1 second per day
Amplitude: 294°
Beat error: 0.1 ms
Lift angle: 52.0°
Frequency: 28,800 A/h

The measured rate deviation is very small and the amplitude appears high in this measurement.
A timegrapher measurement is always a snapshot in one position and does not guarantee future accuracy or the technical condition of the movement.

──────────────────

Case back

The watch has a transparent case back, keeping the automatic movement visible.
Around the sapphire crystal window are the engravings THE LONGINES MASTER COLLECTION, ALL STAINLESS STEEL, SWISS MADE and WATER-RESISTANT.
The polished edge of the case back shows light signs of wear and fine scratches consistent with normal wear.

──────────────────

Crown

On the right side is the original fluted Longines crown.
The crown is signed with LONGINES and the winged hourglass logo. Light signs of wear are also present here.

──────────────────

Band

The watch is mounted on a brown leather strap with crocodile pattern.
This leather strap is not original Longines.
The strap is clearly worn and shows discoloration, wear, creasing and signs of use around the adjustment holes and the attachment to the case. The inside shows clear signs of wear as well.
The strap remains usable, but its condition should be considered as used.

──────────────────

Clasp

The deployant clasp is an original Longines clasp.
It is made of polished steel and features the LONGINES inscription and the winged hourglass logo.
The polished parts show fine scratches and normal signs of wear.

──────────────────

Lug-to-lug circumference

In the current configuration the watch fits a wrist of about 20–21 cm, depending on the adjustment hole used.
Because it is an adjustable leather strap, the fit can be adjusted within the range of the available holes.
