I own a couple of early chronographs including this HEUER - it uses a Landeron movement, metal dial from the 20s?
But my love on single button or 'mono-pusher' chronographs especially with a white enamel dial and the red centre 'tachymeter' scale - so I bough this:
1920s SABINA ‘Monopoussoir’ Chronograph
I can only find a tiny history of the company, and hope someone can identify the movement?
History: Mathez, Paul-Virgile, SA, Montres – SABINA, Tramelan-Dessus
Virgile Mathey registered the ‘VM’ trade mark in 1888. Offered high and good standard quality timepieces.
Here is the watch:
If anyone can help on movement - greatly appreciated
