Hi, thanks for looking. This is an unusual one from my collection. Very much in the style of the Precista divers issued to the Royal Navy. All stainless steel with screw down caseback Seiko quartz movement with brand new battery. Beams Japanese Stores often do collaborations with Seiko, though I haven't been able to dig up any background on this piece. It's got to be JDM. In really excellent condition, very wearable at 40.5mm excluding crown 46mm lug to lug 20mm lugs, it's a total strap monster, ensuring almost every strap looks good with it. Super slim at 8.5mm Bezel action is sweet, very firm, positive clicks. €225 (+ shipping at cost to wherever you're at, I'm in the EU) Similar to Tutima 513, Precista Royal Navy Diver.
