On Friday, while on a market visit, I have come across a watch with nice dial that has captured my attention. This is a new old stock bevelled edge lugs 1920s Early “anonymous” or “sterile” enamel or commonly knmown as porcelain dial chronograph using Valjoux 23 caliber. Inside the movement, there is engraved Arsa. The watch is rather large at 37mm (for a 1920s Watch)..
It is interesting to note that during the hey-day decades of vintage chronographs, many manufacturers sourced parts, cases, movements, dials, etc., from the same manufacturers, and many watchmakers were putting out watches with name and brand-less dials.
This is a new old stock Arsa watch and It features a case which appears largely untouched, with thick and sharp bevelled edge lugs. The dial is beautiful, and features a center telemeter scale AND a pulsations scale.
The watch dial has a tachymeter scale. A tachymeter scale measures how fast an object is moving. The scale can be found either on the dial or in the bezel. Most tachymeters start at 200 and end at 60, but some models can show different numbers. Its very simple to calculate the speed: just mark a point and push the start button. After the object has moved for one kilometer (or mile), push the stop button.
A telemeter scale measures the distance between the user of the watch and the event seen and heard. It was used extensively to calculate when artillery fired. When you saw the light of the shot of the artillery, you would push the start button and push the stop button when the thunder was heard. The number shown in the scale refers to the distance.
I do not have many chronograph watches as I was previously focusing mainly on Rolex Daytonas and 2 Breguet type XX, and 1 Jardur chronograph and one modern Graham Toubilograph tourbillon watch. As such, I have decided to build a small collection of chronograph.
