This is a special and rare Seiko Scuba Master 7K52 200m diver's watch with depth sensor. This technological wonder has no less than 9 hands, with only 2 indicating the time. The remaining hands indicate the calendar, alarm and, more importantly, a lot of dive data: fully automatic dive data... current depth, elapsed dive time, maximum depth, log data, warnings for extreme situations - ascending too quickly, too deep, etc etc. I am no diving expert however and am therefore unable to tell anything about the operation of these functions! Nevertheless, this watch appears to be in top condition. It keeps time in any case. It measures approx. 46 mm in diameter without crown and has a smoothly rotating unidirectional diving bezel, screw crown and sapphire crystal! Everything is included, such as a rubber 22 mm strap - suitable for a wrist of up to 22 cm - the steel and original strap with folding clasp - suitable for a wrist size of only 18 cm! Also comes with instruction manual, tools and the original yellow plastic box with compasses and thermometer + outer box. Therefore a rare completeness. Has minor signs of wear - optically 8.5/10 NO RESERVE! In short: Unique complete and rare top diver's watch by Seiko! Naturally, everything will be carefully packaged and shipped by registered (insured) post.
