Longines Flagship ref. 1003

The Longines Flagship ref. 1003 is an elegant Swiss vintage watch with manual winding, dating from 1959. This model belongs to the classic Flagship collection, one of Longines' esteemed lines, combining understated style, good proportions, and high-quality craftsmanship.

The presented timepiece features a mechanical Longines Calibre 30L movement, a stainless steel case approximately 35.5 mm in diameter, a screw-down case back, a hesalite crystal, and a brown leather strap.

Movement

At the heart of the watch is the Longines Calibre 30L – a renowned Swiss manual-winding movement produced between 1955 and 1967. The Calibre 30L is one of the more recognizable Longines movements from the era of classic mechanical watchmaking.

The movement has 17 jewels, operates at a frequency of 18,000 vibrations per hour, and offers approximately 43 hours of power reserve. It has a diameter of about 30 mm and a height of about 4 mm.

The Calibre 30L is valued for its durability, simple construction, precision, and very good quality of execution. It is a movement sought after by vintage watch enthusiasts and accurately reflects the character of Longines watchmaking from the 1950s.

Case and Dial

The case is made of stainless steel and has a classic, round shape. The case diameter is approximately 35.5 mm without the crown, width with crown approximately 37.5 mm, thickness approximately 9 mm, and lug-to-lug dimension approximately 38 mm.

These are very good proportions for an elegant vintage watch. The case maintains a calm, classic character, but thanks to its 35.5 mm diameter, it remains comfortable and versatile even by modern standards.

The watch features a screw-down case back and a hesalite/acrylic crystal, typical for historical watches. The crown on this particular piece is original, but unsigned. The dial and overall aesthetics of the watch maintain the elegant character appropriate for the Flagship collection.

Strap

The watch is fitted with an 18 mm brown leather strap. The strap complements the stainless steel case well and emphasizes the classic, vintage look of the watch.
