Rescued and restored: Vintage G-Shock DW-5600C Module 691
Picked up this early screw-back DW-5600C in rough shape and decided it deserved a second chance.
The watch came to me heavily worn with deteriorated resin, years of grime, and plenty of battle scars from what was clearly a well-lived life. Underneath it all, though, was an original module 691 and the classic stainless steel screw-back case that made these early squares legendary.
After a full teardown, cleaning, inspection, and rebuild with fresh resin, it’s back on the wrist and ready for another few decades of service.
There is just something special about these early G-Shocks:
Module 691
Stainless steel screw-back case
200m water resistance
Classic square design
Built like a tank
Amazing to think this watch is nearly 40 years old and still doing exactly what it was designed to do.
Restoring vintage G-Shocks is every bit as satisfying as bringing an old mechanical watch back to life.
