Hello, up for sale is my Sinn 900 DLC, a rugged tool watch with Sinn’s signature engineering. This all-black version on bracelet has a bold 45mm case that wears comfortably thanks to short lugs. The matte black dial is highly legible and complements the DLC case and bracelet for a sleek, stealthy look. What makes Sinn special is their engineering: the 900 DLC features a Tegimented case beneath the DLC coating for extreme scratch resistance, Ar-Dehumidifying Technology to keep the movement safe from moisture, and a case built to withstand the toughest conditions. It’s a true tool watch designed with functionality first. The watch is keeping excellent time at -2 spd (see link below for time graph data) and all functions, GMT hand, chronograph, and date are working perfectly. Watch does show some wear, but in my opinion that only adds character to a watch like this. Specs: - 45mm stainless steel case with DLC + Tegiment technology - Black dial with luminous markers - GMT hand + chronograph functionality - Rotating internal bezel - Caliber LJP L120, 42h power reserve - Sapphire crystal with AR coating - 200m water resistance - Screw-down crown - Measurement conversion chart on caseback - Anti-magnetic Set comes with box, manual, OEM DLC bracelet, and an extra leather strap. No warranty card present. Asking $2,300 shipped CONUS. No trades, please. Happy to answer questions or provide more pics. Thanks for looking! Timegraph data: https://imgur.com/a/PODCvjk
