Tissot watch I.D

TIMElyBehaviour · Feb 28, 2024

Hi all,

so I practically got this tissot for nothing. It requires a service which I can do myself. The question I have is can anyone tell me the model or ref?

from a serial number check it was manufactured between 1934 and 1936. The caseback is engraved dated at 1942.

I think it’s a no 319 but can’t be sure.

@Vitezi can probably help.

Based on the "Non Magnetic" text on the dial and the inside caseback inscriptions, this watch was likely manufactured for (and locally cased in) the UK.

The T20 movement serial number appears to be 1104637, which would date the movement to 1940. The watch would have been assembled the same year or shortly thereafter, in line with the inscription on the outside caseback.

The inside caseback number 18561 is a case numbering system used by the local case manufacturer. Tissot often used Dennison as a UK supplier of cases, but I'm unsure if this is a Dennison case or not.

Thank you very much and a big thank you for the extra info in the private chat.

So I completed the service on it today. Was quite an easy one for an old watch. Got it to run at 4+ secs consistently. Very happy. Now I need a new crystal and strap.
