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. There are light hairline scratches on the polished surfaces and slight signs of wear. There are no noticeable heavy dents or damages.

Due to the relatively modest diameter and the classic proportions, the model wears elegantly and subdued.

Dial

An important feature of this version is the silver-colored dial with the fine barleycorn or hobnail motif. The repeating texture creates a subtle relief effect depending on the light.

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

Under 12 o’clock is 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 Longines’ characteristic blued feuille- or leaf-shaped hands.

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

In addition, it features a slim central second 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 shown the date as 20.

Rate: -1 second per day
