Seiko 1970s Dual Logic, a watch that made history. This men's Seiko H127-5000 Digital-Analogue Chronograph watch is highly sought-after; it is the first digital-analogue watch ever. It was made in 1979. The analogue part of the watch (in the top right corner) can be adjusted using the small crown on the top right side. There are no scratches on the crystal. I would advise getting the case polished to make it as shiny as new. This watch keeps time excellently. The case is made of stainless steel; it measures 32.3 mm in diameter (from left to right without the push buttons and crown); it measures 40 mm from top to bottom. Total length of watch and original Seiko stainless steel strap: 23 cm. Ne box or papers. It will be very well packaged and sent via registered mail.
