Introduction to Sinn: a Convergence of Watch*** and Engineering

Like the U2, it's filled with Argon gas and has thesame copper sulphate crystals.It even has chronograph, date, and day complications: a fairly unusual combination for a dive-rated ulysse nardin replica. The blue dial gives it a rather elegant appearance, as well.There's a lot of innovation in the rest of the Sinn catalog as well,and I invite you to take a further look.Related Articles: Extreme Dive ulysse nardin watcheses from TechnoMarine, Bell & Ross, MTM, and SinnBy Paul Hubbard .The Sinn U2Next up is the Sinn U2, a mechanical diver's ulysse nardin based on the ETA 2893 movement. This adds an independently settable 24-hour hand which makes it very useful for traveling. The U2 is filled with Argon gas, and that odd hole in the 6 marker is a copper sulphate indicator that tells you if the Argon needs to be replenished -- the idea being that you can tell if moisture has seeped in or the seals have weakened. Clever, since you should notice immediately just by reading the time. The copper sulphate capsules (there are actually two of them) also absorb moisture to keep the movement nice and dry.Like the UX, the U2 it's made of tegimented submarine steel, with a hardenedanti-reflective coating on the sapphire crystal, and a super-hard machinedbezel. I really like the face of both the UX and the U2: functional, unique,and very legible.The Sinn ArktisLastly, the Sinn Arktis. For this one, I quote directly from Sinn:A Sinn for exceptional conditions was created in intensivecooperation with the internationally famous extreme diver MarioM. Weidner: A mechanical diver’s chronograph that is not only pressure-resistant to 300 meters of water depth, but also guarantees rateprecision and reliable functions at unusually cold temperatures. Itpassed the endurance test at the North Pole with flying colors.While "only" water resistant to 300 meters, and made of "ordinary" stainlesssteel, the Arktis is notable for its wide functional temperature range of -45°C to80°C, thanks to their use of a custom oil that lubricates the movement
