The ultimate tool watch to get! This Sinn 856.S (S standing for schwartz, or black in German) UTC is a GMT-version of the regular 856. This watch features all you need and will get you through pretty much any scenario you'd find yourself in. It's rated 200M WR, but also vacuum resistant. The case itself allows for magnetic field protection up to 100mT, and has a built-in dehumidifying Ar-gas technology to prevent any fogging with rapid pressure changes. The screw-down crown allows for easy setting of all the functions.  The 40mm case is slim at 11mm, with a 20mm lug width. The crystal is AR coated on both sides for some of the best legibility in the game (see pictures on wrist, with one wrist shot trying to show as much glare as I could get). The black hard coating is done using Sinn's tegimented proprietary technology, and it really shows well on this watch. The watch head is practically free of any wear marks (except the smallest rubbing by 12, see pictures). The bracelet shows a bit more wear, but that's also a higher contact area (see pictures). The watch comes sized for my 7" wrist, and includes 3 additional links (2 used, 1 new), the original screw driver and strap tool from Sinn, the instruction manual/CD, signed warranty card, original inner box, and outer box. I'm also including a brand-new, unworn NATO strap (thin material for comfort) with matching black hardware. Letting this one go because I just picked up a new world timer and GMT, so I (unfortunately) need to make some space in the watch box (you know how it goes). Price: asking $1595 or OBO. PayPal F&F preferred, but happy to do G&A if you absorb the fee. Free shipping with USPS Priority Mail, fully insured, for US.
