How do I correctly change the strap on this Certina?
To change the DS-4 strap, proceed with a springbar tool or fine screwdriver: position the tool on the lug pin laterally and exert gentle outward pressure to release the pin from the spring retainer. Repeat on the other side. Exercise caution to avoid scratching the case. Insert the new 20mm strap by aligning the pins with the lugs.

What is the average lifespan of a leather strap for the DS-4?
A quality leather strap with vegetable tanning has an average lifespan of 3–5 years with daily wear, varying according to climate, sun exposure, and humidity. Leather naturally wears at the lug attachment points and in the buckle fold zone. Periodic maintenance—gentle cleaning, hydrating treatment every six months—significantly extends the useful life of the strap.
