Strap for SeaQ Chronograph Stainless Steel / Blue / Synthetic - Folding

The SeaQ 1-37-23-02-81-09 features a lug width of 21 mm. This measurement is taken from the outer shoulder of one lug to the outer shoulder of the opposite lug, and is essential for selecting compatible straps. MilanoStraps offers an extensive selection of straps specifically dimensioned for this specification.

Recommendation depends on intended use. For formal-sportive aesthetics, we suggest alligator with vegetable tanning (dark brown or café tones), which develops rich patina over time. For aquatic versatility, a heavyweight 1.6 mm NATO in navy blue. For maximum technical operability, a black FKM rubber strap. At 43.20 mm case diameter, each option maintains correct visual proportions thanks to the 21 mm lug width.

Strap replacement is executed via the case's lateral lugs. Use a spring bar tool to gently compress the internal springs of the lugs: maintain downward pressure whilst extracting the bar. Insert the new bar perpendicular to the lug hole, then release. The operation requires care to avoid scratches on the ceramic and steel case. We recommend professional intervention at a specialist atelier if uncertain.

Yes, provided they respect the 21 mm lug width specification. MilanoStraps offers certified compatible artisanal and aftermarket straps in leather, NATO, and rubber. Always verify that the strap lugs are cut for 21 mm and that the thickness of the lug bar is appropriate for a ceramic and steel case—materials requiring robust lugs to prevent concentrated stress.

A vegetable-tanned alligator strap typically lasts 3–5 years with moderate use and regular maintenance (gentle cleaning, drying after saltwater exposure). Intensive use in aquatic environments reduces durability. A calf strap, being more delicate, may last 2–3 years. FKM rubber is virtually indestructible but may yellow after 5–7 years. On sports watches, many collectors prefer rotating between multiple straps to extend overall lifespan.
