Strap for DS 4 Black

The lug width of the Certina DS-4 C0224101105000 is 20mm, the standard measurement for wristwatches in this dimensional category. This means any strap compatible with this lug width will fit perfectly onto the two lugs of the case without play or excessive tension.

The Certina DS-4 pairs excellently with quality leather straps, particularly crocodile or alligator with vegetable tanning, or naturally tanned calf leather, which enhance the understated steel case aesthetic. For a more versatile and casual approach, a cotton or canvas NATO strap maintains the pragmatic character of the model. A vulcanised rubber strap represents the ideal choice for sports use or humid conditions.

The strap change is performed using a specialised tool (spring bar tool) that allows compression of the internal springs at the case lugs. Once the spring is compressed, the old strap extracts laterally. The new 20mm strap is inserted by aligning the lug width with the holes on the case attachments and allowing the spring to lock into position. The operation requires care to avoid scratching the case.

Yes, the 20mm lug width provides access to a wide selection of artisanal aftermarket straps. At milanostraps.it you will find straps in fine leather, NATO, rubber and special models in shell cordovan, alligator and vegetable-tanned calf, all ready for dispatch and customisable according to your colour and finish preferences.

An artisanal leather strap made with vegetable tanning has an average lifespan of 3 to 5 years with daily use, varying according to climatic conditions, humidity exposure and cleaning frequency. Natural leather acquires patina over time, improving aesthetically, but wear of the vegetable fibre is an inevitable process. Shell cordovan straps tend to last slightly longer than standard calf leather.
