Catalogue description

Dealer description — Bulang & Sons

MAVs Faithful Companion This is a very early example of the Lemania 5100 run Porsche Design Chronograph. Dated to the 1970s this Ref. 7176 features a non screw down crown. The 42mm case is in a pretty condition, with the black PVD coating showing only minor marks. Which I very rarely seen as this watch is one of the very first wristwatches to feature PVD coating. The quality and technique not comparable to what we can see on similar watches with same finish. The black dial features three sub dials and also a cool orange stopwatch hand. The lume has taken on a nice patina over the years. The watch has its original bracelet that is also in good condition. The watch is offered in a curated package accompanied by the MAV GREEN LEATHER WATCH STRAP and one of the only 10 ever made CUSTOM UPCYCLED MVRK DOCUMENT CASEs.

Historical context

Quartz Revolution (1969 – 1990)

Seiko's Astron begins mass quartz timekeeping; traditional industries contract sharply.

Quartz and digital watches transformed the market after 1969. Swiss employment collapsed, Japanese and Hong Kong production soared, and the Swatch (1983) helped the Swiss industry recover; mechanical watches survived as luxury goods.

Atlas type guide

Chronographs and split-seconds watches

A chronograph is a watch with an additional seconds hand that can be started, stopped and returned to zero independently of the timekeeping. Louis Moinet built an early example in 1816 and Nicolas Rieussec a recording 'chronographe' in 1821; Adolphe Nicole's heart-shaped reset cam (patented 1862) made the modern return-to-zero possible. Split-seconds (rattrapante) chronographs add a second hand that can be stopped for intermediate times; flyback chronographs restart instantly.

Chronographs were essential tools for doctors (pulsometer scales), artillery (telemeter), engineers and sport. In wristwatches, Valjoux, Venus, Lemania and later the automatic chronographs of 1969 (Zenith El Primero, the Chronomatic Calibre 11 group and Seiko 6139) are milestones.

What to look for

Push-pieces on the case band or a single button in the crown (monopusher).
Subsidiary registers for minutes and hours; tachymeter, telemeter or pulsometer scales.
Column wheel versus cam control visible in the movement.
Calibre markings of specialist makers (Valjoux, Lemania, Venus, Landeron).

Dating clues

Pocket chronographs with heart cam reset: after 1862.
Wrist chronographs: from c. 1910; two-button designs from the 1930s.
Automatic chronographs: from 1969.
