This is an excellent condition Mens San Martin BB58 Tudor Homage Automatic Diver Watch. This is a 40mm case size watch with PT5000 movement, similar to the ETA 2824. The watch looks near new and works correctly. I have two for sale. This is the medium-dark blue model. This one has bracelet still in wrap. This model didnt work out well for me, so selling. It also comes with a Scurfa Rubber strap with curved spring bars, and a black nylon strap. The only blemishes are tiny marks from changing to rubber strap, then putting bracelet back on. This model has tubes and very small screws on each link, so care needs to be taken not to lose a screw. Very nice lume and bezel action and alignment is very good. The watch comes with 3 tools for making adjustments and strap changes.
