Estimated year of manufacture
Based on the reference L2.708.4, the Longines caliber L602 used, and the Master Collection execution, this piece is estimated to be from about 2005–2010.
The Master Collection was introduced in 2005. The L2.708 series is part of the first generation of this collection and uses the automatic caliber L602. A comparable piece with reference L2.708.4 and caliber L602.2 is dated for example 2008, while another documented L2.708.4 from 2007 is known. ([clarence.ch][3])
Therefore, a period of roughly 2005–2010 is plausible for this specimen. An exact production year cannot be determined with certainty from the photos provided and the visible case markings alone.

Case

The case is stainless steel and presents a classic round dress-watch shape with relatively long and slightly angled lugs.
The diameter is about 38.5 mm without the crown. The case features a fine, smooth bezel, which makes the black dial appear larger and gives the watch an elegant look.
The case and bezel are predominantly highly polished. In the provided photos, there are light superficial scratches and normal signs of use. There are no significant dents or deep visible damage.
The shape of the case and lugs appears well preserved in the photos.

──────────────────

Dial

The black dial has a fine, clearly visible structured finish that stands out more or less depending on the lighting.
Under 12 o’clock sits the LONGINES inscription and the winged hourglass logo.
The hours are indicated by large silver Roman numerals. Around the outer edge is a separate minute bezel with fine indices and five-minute Arabic numerals.
The hour and minute hands are elegant feuille shapes. A long, slender central seconds hand provides the seconds display.
At 3 o’clock is the rectangular date window. In the supplied photos, the date shown is 19.
Above 6 o’clock is AUTOMATIC. Just below is the semicircular power reserve indicator with a small hand and a finely graduated scale.
At the bottom is SWISS MADE.
The dial appears very clean in the provided photos. No obvious stains, discoloration, or major damage is visible.

Movement

Type: Automatic mechanical
Caliber: Longines L602
Jewels: 21
Frequency: 28,800 vph
Power reserve: Approximately 42 hours
Functions: Hours, minutes, central seconds, date and power reserve indicator
Official Longines documentation associates reference L2.708 with caliber L602 and indicates a 42-hour power reserve.
The automatic movement is visible through the transparent case back. The rotor is decorated with Côtes de Genève stripes and the gold inscriptions Longines and L602.2.
Additionally, several movement components are visible through the back.
On the supplied timegrapher image, the movement was measured operating with the following values:
- Rate deviation: -11 seconds per day
- Amplitude: 289°
- Beat error: 0.0 ms
- Beat rate: 28,800 vph

These values are only a snapshot of the movement’s performance during measurement and do not guarantee long-term accuracy or condition.

Power Reserve Indicator

A characteristic feature of this Master Collection is the mechanical power reserve indicator at 6 o’clock.
The semicircular scale shows how much energy remains in the mainspring. The small silver hand moves along the fan-shaped scale.
The caliber L602 used has a maximum indicated reserve of about 42 hours.
This complication gives the display a technical element without sacrificing the watch’s classic look.

──────────────────

Case back

The back features a transparent case back allowing a view of the automatic movement.
Around the transparent back are several engravings, including THE LONGINES MASTER COLLECTION, ALL STAINLESS STEEL, SWISS MADE, and the individual serial number of the watch.
Thanks to the transparent part, the decorated rotor is clearly visible. It reads Longines and L602.2.
The combination of a visible case back and decorated movement is characteristic of this Master Collection version.
On the polished parts of the back, there are faint signs of wear.
──────────────────

Crown

The crown is fluted for easier winding and setting.
On the outside is the winged LONGINES logo in a sandglass shape.
From the supplied photos, the crown appears to correspond to the execution and finish of the watch.
