Christmas gift from my son

Hello everyone,

My son just showed me what he got me for Christmas. Here is my first 1950s Tissot. It's running, but he and his watchmaker mentor will be doing a service on it. Plus, replacing the crystal & case back seal. Should this have a Tissot signed crown, or is this the correct crown for this model? It has a caliber 28.5-21. I was wondering if this is one of the Omega/Tissot movements?
Would anyone know either what model this is or where I might find it? I looked up the serial number and from what I determined it was made in 1952.

That's a charming watch and a great gift. Once it's cleaned up, it will be appealing on the wrist, and I'm sure you will enjoy the bumper movement. It appears to have had some water intrusion at some point, so hopefully any issues can be addressed during the service/repair.

@Vitezi might know if the crown is original. I will say that the style of the crown is certainly period-correct.

Thank you so much for your reply. It definitely needs a new case back seal for sure. Is the water damage correctable? Is there water damage on the dial?

Obviously the hands and dial show damage, and some of it is probably due to water. But in your place, I wouldn't worry about it or try to fix it. Together with the radium burn on the dial, the watch has a charming and honest appearance, and I would thoroughly enjoy it for what it is. Much better to have a dial like this one, that shows some age, than one that has been repainted. Any corrosion in the movement will obviously need to be addressed, but it's quite possible that this was already done during a previous service.

Definitely encouraging words and great advice. Thank you so much. I would definitely love to know it's story. I noticed and mentioned the case back edge to my son so he can get that cleaned up for a good seat to the seal along with a new seal.

Is there any worth in trying to clean up the hands? If so, who could we go about doing so? This is completely hypothetical as I do love the watch.

It looks like some of the plating on the hands has been lost due to corrosion. But that's just my opinion based on your photos. The luminous paint is also darkened on the hour hand, usually due to water and/or mold. The best thing is to learn to love it, as I mentioned previously.

Options generally involve various levels of restoration, typically not cleaning. The luminous paint can be removed from the hands and new color matched compound can be reapplied. That's not too difficult for an experienced watchmaker to do, but beware that the existing paint is radioactive so it should be handled with care. And if you choose to do it, you should probably replace the paint in both hands so that it matches. The person doing it can try to get a reasonable match with the lume on the dial markers, but don't expect perfection. If the darkened lume in the hour hand really bothers you, this wouldn't be a crazy option to consider.

The hands themselves can be stripped and re-plated, but then they will be shiny and they won't match the applied dial markers. If you do this, you should do it for all three hands, but I really don't recommend it because the condition of the hands will be dissonant with the rest of the watch.

I definitely love it as is. To me it adds to the character of the 72 year old watch. . Thank you for your replies

Nice watch.
I think the crown is correct and original to the watch.
This is mine of the same period.




Other references but same crown

Should this have a Tissot signed crown, or is this the correct crown for this model?
Yours is an early '50s watch so that style of crown is correct and possibly original. Signed Tissot crowns started to appear in the mid-1950s.
It has a caliber 28.5-21. I was wondering if this is one of the Omega/Tissot movements?
Yes, that's a Tissot "bumper" automatic movement, variants of which were used on all their automatics from the late 1940s through the early 1950s.
Would anyone know either what model this is or where I might find it?
Yours is a reference 6548, version 7, as seen on the inside caseback.

Congratulations on your first Tissot 😁
