The Vintage Wrist Watch Company has dated this piece to the 1950s.
The watch has a 28.5T-21 bumper automatic movement which is working nicely.

Early automatic movements such as this one relied on the rotor ‘bumping’ backwards and forwards between two springs to maintain the power within the movement. Later automatic watches have the fully rotational rotor.

The watch measures 34mm diameter excluding the winding crown and the lugs. The case is stainless steel and overall, the condition is good with just general light surface marks. The screw-on case back has some scratching where a tool has slipped in the past. The case back states that the watch is waterproof but, as with any vintage watch, it should be kept away from water and moisture. The inside of the case back is signed Tissot.

Later plain winding crown.
The lens is in lovely condition.
The signed dial is in its original finish with original hands and seconds sweep. The dial has built up a lovely warm finish with age.
A new leather strap has been fitted.
The watch comes in its Tissot presentation box, a bit tatty but still good to have.
