Seiko 6309-729A SDEB39 "Turtle" 1987 Automatic Day/Date Gentleman's Divers Watch


Looking superb with a new Seiko dial! - This is a lovely pre-owned Seiko 150m scuba divers' automatic men's watch from 1987. It has a brand new Seiko Stainless-Steel bracelet strap ( which will fit a 7.75-inch wrist),  complementing the new black dial. It has a Seiko 17 jewels calibre 6309 automatic movement which is in great working order. As this watch is used, everything has been professionally dismantled, cleaned, and polished in order to ensure the watch is presented in the best condition possible. However,  due to the age of the watch, some minor wear and usage marks might be present. This is a classic Seiko divers watch and will give the wearer a classic look.


The Seiko 6309-729A "SDEB39 / Turtle" is a 41mm men's automatic watch with a stainless-steel case and a blue analogue dial protected by hardlex crystal. It uses a 6309 calibre self-winding mechanical movement that cannot be manually wound or hacked (the second hand does not stop when the crown is pulled out). It ticks 6 times per second which gives the second hand a smoother movement than quartz watches which tick once per second. The watch should run for up to 47 hours when fully wound and will self-wind when moved.
