Discontinued watch (circa 2016) from Sea-Gull. For a period of time, the company made a limited number of these Omega Aqua Terra homage watches. It is a 39mm dial with double-domed sapphire crystal, a mineral glass display back, and 18mm lugs. The display color is blue, although I'd describe it more like a light blue, rather than the deep dark blue of the Omega Aqua Terra. I have never seen Omega's summer blue in person, so I do not know whether this watch is anything like that one. Watch is rated to 20 atm, although I've never tested the waterproofing. I am the second owner of this watch. The original owner upgraded the movement to a hand-winding and hacking auto DG2813 movement from Ofrei, and he re-lumed the hands with blue-emitting NoctiLumina. I have not had the watch serviced since I acquired it. However, while I do not wear the watch often, I found that it kept pretty accurate time. In the past 24 hours, I'd say it has gained 2 or 3 seconds. Because I've owned this watch for nearly 10 years, there are the normal wear-and-tear scratches, including to the bracelet, as well as lug marks from strap changes As for flaws, the date is misaligned a bit to the left and there are 2 holes in each lug (full info in this thread: https://www.watchuseek.com/f71/sea-gull-seamaster-back-stock-limited-availability-3370594.html). However, these flaws never bothered me. Will include the original box and papers, along with extra 18mm straps that I have lying around. This will include a Eulit perlon strap.
