Strap for SeaQ Chronograph Stainless Steel / Silver Screen / Bracelet

The lug width of the SeaQ 1-37-23-03-80-70 is 21 mm. This measurement is precise and consistent across all examples of the reference. To verify it, use a digital calliper measuring the distance between the internal edges of the lugs (the metal appendages that attach the strap to the case).

The ideal strap depends on intended usage. For formal or professional contexts, we recommend leather in vegetable tanning or alligator in dark shades (black, brown, cognac); for nautical or sports use, a treated rubber or NATO fabric strap ensures minimal maintenance and resistance to salt humidity. Shell cordovan leather develops natural patina over time, whilst synthetic materials maintain uniform appearance.

Strap change requires minimal tools: a spring bar tool (spring bar remover). Position the watch on a soft surface, insert the tool into the lateral hole of the elasticated bar, apply gentle pressure to release it, and pull outward. Repeat for the other end. Once the old strap has been removed, align the holes of the new strap with the lugs and reinsert the bars until audible click.

Yes, any strap manufactured for 21 mm lug width is compatible with the SeaQ. MilanoStraps offers a complete collection of leather straps in artisanal, alligator, NATO and rubber in the 21 mm measurement, selected for aesthetic coherence and build quality with this model.

Durability depends on usage and material. A high-quality leather strap with vegetable tanning typically lasts 3–5 years of moderate daily wear. Frequent exposure to humidity (as with a tool watch rated 300 metres), perspiration and direct sunlight accelerates ageing. Vegetable tanned leather develops patina, whilst shell cordovan tends to curl. To maximise durability, we recommend rotating with alternative straps and drying thoroughly after prolonged water contact.
