The dial should be like this, although 3 variants are known , the back of the 7 is the point where the difference can be seen.
Here is a "straight" 7, there are two more…a straight 7 with a difficult to see small "foot" and the curved one ( like yours)
ALL have the T above the six and may have a 3H print. ALL have full numbers without cutoff. The only variant with no T is the later superluminova dial with the clipped numbers at the subdial and therefore no T and no 3H as there was no tritium anymore
Looks okay but photos are bad...but this watch shows no photos of the engravings and has a"thick" plexi (Sinn aftermarket). The case parts are not fitted correctly, not in line..are you looking for a second one?
Cheers Dirk
Sure there is a plexi in all 1550,but they are flush with the bezel, the case parts are misaligned, you can see at the plexi which is higher on one side and the caseback is uneven fitted to the case
thank you friends. Well, I have concluded that I will take the original one I got from the auction . It is perhaps a service dial by Sinn but the bezel is good , the watch came from a solid collector and at least I won't be on the blacklist 😀 .
