For sale we have a classic mid 1960s Le Cheminant watch, known as the ‘Invincible’. It is a good quality and adaptable watch, designed to be a daily wear or a dress watch dependent on preference. 
It has a 34mm case diameter, with a depth of 11mm and a lug-to-lug measurement of 42.25mm. This gives it an impressive presence on the wrist. The gold plate is a relatively even tone and is in good condition with little signs of wear. 
The dial is very well executed on the watch. It is a silver base tone which has a satin sunburst finish radiating from the centre, which plays with the light. The hour markers are well designed with long baton markers, a wedge to differentiate 9 O’clock, plus balance the date window, and stylised Arabic numerals at 12 and 6. The date window has a bevelled edge, easing the eye towards the date. The signing is good and clear with no wear.
The luminous facetted dauphine style hands are original and were very much on-trend in the mid 1960s. 
To the rear is the steel screw back which is signed with the reference 330-1150, with brushed finishing. 
Inside is the reliable, robust and accurate Felsa calibre 4700N. It is a bi-directional automatic movement with incabloc shock protection and a jewel count of 25. It is functioning well, keeping time to within +15 seconds a day.
 
I think the pictures really speak for this watch, highlighting the quality of the dial design and finishing, paired with the case with elongated lugs providing presence. It is a very adaptable watch that can be worn in many situations. This makes it the ideal vintage every day wear.
