Strap for SeaQ Date Stainless Steel / Green / Rubber - Folding

The Glashütte Original SeaQ 1-39-11-13-83-37 features a 20 mm lug width. This dimension is specifically proportioned to the 39.50 mm case diameter and determines which strap you can install. To verify it, measure with a calliper the internal distance between the two lug ears: it must be exactly 20 mm.

The ideal strap depends on intended use. For formal or business contexts, we recommend smoked alligator with vegetable tanning or shell cordovan. For authentic marine functionality, gummed calf or hand-dyed cow leather offer durability. For quick changes and maximum water resistance, vulcanised rubber or NATO straps remain the most coherent choices aligned with the watch's spirit.

Strap replacement requires extraction of the spring bars connecting the strap to the lugs. Use a dedicated spring bar tool to push the bar from one side and free the lug. Remove the old strap and insert the new one, aligning it precisely with the lugs. Verify both spring bars are securely fastened before wearing the watch.

Yes, all straps with a 20 mm lug width are compatible with the SeaQ. Milano Straps offers a curated collection of artisanal leather straps, synthetic materials and textiles, specifically selected for 20 mm watches. Compatibility is guaranteed by standardised lug width specifications.

A quality leather strap with vegetable tanning, worn regularly, has a lifespan of 3–5 years. Longevity depends on exposure to moisture, perspiration and UV rays. For the SeaQ, which frequents marine environments, we recommend rotating multiple straps and treating the leather with dedicated balms. Rubber or NATO straps offer greater durability (5–7 years) under intensive use.
