Certina DS watch combines elegant, precise and practical in one, extraordinary movement by the beautifully polished 40mm 316L stainless steel case wrapped with matte polished bezel and lugs.

This Certina DS Calibre 25-65 watch has a special place in my collection. I wore this watch until it “suddenly” stopped 4years ago. I delivered it to a local watch store in Oslo just before setting off for the Danish school of Watchmaking, but he never got around to servicing it. I picked the watch up last time I was in Oslo and now it is time to get it running again.

One detail that attracted me to the Certina DS Calibre 25-65 watch was the impressive Turtle on the case back.

Movement is in nice condition.

The dial is in fairly good condition.

The dial and hands removed.

There is plenty of dirt in the movement so no wonder it suddenly stopped

I remove the auto-winder bridge.

The movement is also missing a bridge screw.

Here you can see the gear train layout.

There is plenty of dirt in the barrel.

The movement has been cleaned and I have just put the balance jewels back in place to see that the balance moves freely.

I have a new mainspring.

The movement is coming together nicely.

The movements is back together and ticking.

Not a bad result considering it was an non-running watch.

I place the movement back in the case and it looking clean and nice.

I have brushed of the dial and replaced the luminous compound and the result is great.

It’s a sunny day as the watch comes back on my wrist after 4 years! It’s got some battle scars, but that it survived several decades followed by my teenage years and ticked to tell the tale well into my 20’s before taking a well earned break. I would say it might just be on of the toughest watches in the world!!!
