Debut on the wrist for a 1968 first iteration Certina Argonaut 220m. Really liking the chunky case (clocks in at a respectable 37mm), bakelite bezel, how the rectangular hands are complemented by the square lumes and angular lugs, and the in-house 25-651 movement. Feels like a proper tool watch, rugged outside and in, from a company that took the task seriously (https://www.vintagecertinas.ch/en/certina-divers-watches/) 👍
I herby declare I have had enough of 100 degree weather and all this humidity but it’s Friday and the clouds look nice and fluffy and I really like the simplicity of this old KS dial so I’ll call it even
