For sale the wonderful compressor style diver from Alpina: the Seastrong Heritage in white. The watch was purchased used last year, then I sent it to the company for an operational check and authentication service. It is therefore sold as a full set, with papers and authentication certificate which certifies that the watch complies with the company's specifications as of 22-2-24. The watch is sold including: original rubber strap (meticulously cleaned of any skin debris), Watchgecko black leather strap (for a dressy and elegant look) and finally Watchgecko mesh bracelet, ideal for summer. This makes the watch very versatile, suitable for every look. The leather strap and bracelet come with quick release pins. On the day of the sale, I include a reading on the Timegrapher, after having worn the watch for an hour and having fully charged it. Worth noting: in addition to the normal hairlines, two micro bumps (tiny size and visible only in macro photos) in the terminal portion of the lugs. Since the lugs are very curved, they are virtually invisible, as well as being easily fixable. I slightly worked on the attachment of the watchgecko bracelet with a dremel, as it was not perfectly compatible even if it was 21mm. Now there is a perfect fit, as visible. Before the sale I require contact with the buyer, to see every single aspect and doubt about the watch. Priced at 900$ with a (reasonable) margin of negotiation
