Today I'm putting up for sale this superb watch from the Sinn 556i series, the 556 I B,. This reference is characterized by a 316L stainless steel case with a sanitized finished that finds the perfect balance somewhere between brushed and polished, a no-date electroplated blue dial with a sunburst decoration, sapphire on both sides with double AR coating on the front and interior AR on the back, screw down crown with 200m WR, diamond-cut rhodium-plated hands and appliqués, with lume on the hour and minutes hands and the hour indices. Wears brilliantly on any wrist size at 38.5mm in diameter and 11mm thick. This is full kit, still under warranty until March 2024. Includes a bonus Uncle Seiko president bracelet with fitted end links, giving the steel bracelet fan the option to switch up the look - or keep the stock bracelet clean for better resell value down the road when it's time for something new. With a 20mm lug width, this one will also wear great on a wide variety of straps.
Condition: At just just over a year old, only a few superficial marks or hairlines on the case and bezel that one might expect with some regular but careful wear. Nothing I found noticeable on the wrist. Minimal rash on the original bracelet. Looks like the prior owner wasn't the most careful with the pin removal when sizing the bonus Uncle Seiko bracelet, so the polished sides are a bit marked up, but the main brushed surfaces are in good shape. Crown movement is smooth, and watch is keeping good time. Kit is fully intact, with inner and outer box, manual, warranty card, hang tag and tools.
Price: The last one of these posted on here had an ask of $1980, plus shipping, and was three years old, and thus out of warranty at the time of posting. I'll offer this one at $1980, shipped, still under warranty, including the bonus bracelet.
