Omega Aqua Terra annual calendar 38.5mm reference 231.13.39.22.02.001. Box, manual, pictogram card (no warranty card) and authentication certification included. Comes on Omega dark brown alligator strap and deployant clasp. I've also included a burgundy Vario vintage leather strap w/ quick release pins as I'm sure not everyone has a bunch of 19mm straps lying around. However, as you will see in the album, you can squeeze in a 20mm strap using 19m pins (the blue and brown ostrich leg straps are both 20mm--these are NOT included in the sale, but just to show options). Specs: 38.5mm case diameter; 14.5mm thickness including sapphire crystal (the extra thickness is due to the 8601 coaxial annual calendar movement compared to the 8500 in the standard ATs); 45.5mm lug to lug; 19mm lug width. The watch is a great size and should work w/ most wrist sizes and even as a unisex option. For anyone not familiar w/ the annual calendar function, it allows you to only have to change the date once/year between Feb and March assuming you wear the watch continually or keep it on a winder. In other words, it automatically accounts for the 30 day months. The Sedna gold indicies and hands really shine in natural light. I tried to capture this in some of the photos but you have to see in person to truly appreciate. Watch is in great condition. Some typical hairline marks can be seen on the polished bezel but these can easily polish out if you want. This is definitely a dressier version of the AT, but you could dress it down w/ a good rubber strap. **$3100** Paypal F/F or Zelle. I'll cover shipping to CONUS or Canada. In person sale in Tucson or Phoenix also available on request.
