Case

The Flagship series belongs to Longines’ classic dress watch lines. This L4.799.3 features a round case of about 35.5–36 mm, giving the watch a traditional and relatively understated size.

The case is finished in polished stainless steel and paired with a gold-colored bezel. The stepped shape of the bezel gives the watch a distinctly classical look and sits nicely with the gold-colored parts of the bracelet.

In the supplied photos there are clear signs of wear, mainly on the gold-colored bezel. It shows scattered superficial scratches and small signs of use. The polished stainless steel parts of the case also show light scratching, consistent with normal wear.

The case shape and lugs otherwise appear neatly preserved, with no large dents or heavy damage visible.

Dial

The champagne-colored dial is a striking feature of this piece. The surface has a fine radial sunburst finish, causing the color to vary with light from light champagne to a warmer gold.

Below 12 o'clock are the LONGINES inscription and the well-known winged hourglass logo. Above 6 o'clock is AUTOMATIC.

Hour positions are set with diamond indices in small square settings. At 12 o'clock there is a double diamond index, while the other positions—with the exception of the day/date window position—have individual diamond indices.

The gold-colored hour and minute hands have a slender, classic form. A very thin central second hand completes the time indication.

At 3 o'clock there is a combined day and date window. In the supplied photos it shows TUE 24.

At the bottom of the dial is SWISS.

The dial itself appears very neat in the photos. There are no noticeable stains, heavy discoloration, or damage visible.

Movement

Type: Automatic mechanical
Caliber: Longines L636.5
Base caliber: ETA 2836-2
Functions: Hours, minutes, central second, day and date
The automatic movement is visible through the transparent case back. On the rotor the markings L636.5 and Longines are clearly visible.
The ETA 2836-2 forms the base of this Longines caliber and is an automatic movement with central second and combined day-date function.
The gold-colored rotor provides a nice visual contrast with the other silver-colored components of the movement.
No timegrapher measurement is supplied. The exact rate deviation, amplitude, and beat error cannot be determined from the photos.

Day-and-date display

The watch has both a day and a date display.
Both functions are combined in one elongated window at 3 o'clock. The day indication is on the left and the date on the right. In the photos the indication shows TUE 24.

This configuration is characteristic of the used L636.5 caliber and gives the watch, in addition to its classic look, a practical daily function.

──────────────────

Diamond dial

This piece is equipped with diamond hour markers instead of the more common baton indices.
The diamonds are separately set in small square metal settings. The 12 o'clock position is recognizable by a double diamond setting.
Together with the champagne sunburst dial and gold-colored details, this gives the Flagship a more luxurious appearance than standard versions with simple indices.

──────────────────

Back

The case back features a large transparent viewing window through which the automatic movement is visible.
The rotor bears the Longines signature and the caliber designation L636.5. Around the window is a polished metal rim with engravings.
In the photos there are light superficial signs of wear on the steel parts of the back. The transparent portion looks clear enough to view the movement well.

──────────────────

Crown

The crown is made of stainless steel and has a ribbed outer edge for grip when setting the time, day, and date.
On the outside LONGINES is engraved.
The crown shows light signs of use in the detail photo but otherwise looks neat and appropriate for the watch.

──────────────────

Bracelet

The watch is equipped with the original bi-colour Longines metal bracelet.
The bracelet consists of several narrow links with polished stainless steel combined with gold-colored center links, creating a consistent two-tone design across the case and bezel.
The bracelet features an original integrated Longines butterfly/folding clasp. Both LONGINES and the winged hourglass logo are clearly present on the clasp.
On the polished steel and gold-colored links there are normal superficial signs of wear and scratches. The gold-colored links, in particular, show more noticeable signs of wear in some places.
Based on the supplied size photo, the current bracelet appears suitable for a wrist circumference of approximately 18.5–19 cm.
