Vintage c.1935–1939 “Le Locle” Swiss Manual Wind Watch – Peseux Cal. 66

A wonderfully characterful pre-war Swiss wristwatch, dating most probably to the second half of the 1930s.

The aged dial is signed LE LOCLE, taking its name from the historic Swiss town which has been one of the country’s most important centres of watchmaking for centuries.

Rather than representing the movement manufacturer, the Le Locle signature is most likely a private-label or retailer identity – a common practice within the highly fragmented Swiss watch industry of the period.

Most importantly, the movement itself can be identified.

Inside is a Swiss Peseux calibre 66 manual-wind movement, part of the Peseux 60-series family introduced during the mid-1930s. Peseux was a specialist Swiss ébauche manufacturer whose movements were supplied to numerous watch companies and assemblers.

The watch therefore most plausibly dates from approximately 1935–1939, making it around 90 years old.

It has a lovely period appearance, with large stylised Arabic numerals, railway minute track, blued-style hands and subsidiary seconds at 6 o’clock. The dial has developed extensive age-related patina, crazing and deterioration which, to my eye, gives the watch enormous character. Please study the detailed photographs carefully as these form an important part of the condition description.

The steel-tone case measures approximately 28mm across excluding the crown and 36mm lug-to-lug.

It is currently fitted to a vintage-style expanding metal bracelet which will comfortably accommodate wrists up to approximately 17–17.5cm. This is easily replaced should the new owner prefer a leather strap.

The crown winds and sets correctly and, most importantly, the watch is running well at the time of listing. Given its considerable age, however, no guarantee of future accuracy or service history can be given and a service is always recommended for regular use of a vintage mechanical watch.

The case, crystal, dial, hands and bracelet all show wear commensurate with age. In particular, please note the substantial ageing and patina to the original-style dial shown clearly in the photographs.

A fascinating surviving example of the Swiss ébauche watchmaking industry of the pre-war 1930s, powered by a genuine Peseux mechanical movement.

Watch only – no box or papers.
