Strap for SeaQ Date Stainless Steel / Blue / Rubber / Pin

The lug width of the SeaQ 1-39-11-09-81-06 is precisely 20 mm. This measurement is determined by the case geometry and should be verified using a calliper positioned between the lugs where the strap is inserted.

For the SeaQ, we recommend alligator leather in neutral tones (black, dark brown, navy blue), shell cordovan for a more precious choice, or vegetable-tanned calf leather for those preferring a structured texture. For underwater use, a satin rubber strap remains the most functional option. Strap length should typically be 120–130 mm on the top section and 80–90 mm on the bottom.

To replace the strap on the SeaQ 1-39-11-09-81-06, you must remove the spring bars using a dedicated bar removal tool. Position the watch on a soft cloth, insert the tool into the lateral holes at each lug, and apply controlled pressure to slide the bar out. Once extracted, remove the old strap. Align the new 20 mm strap with the lug holes and reinsert the spring bars using the same tool, ensuring smooth, even insertion without forcing.

Yes. Any strap with a 20 mm lug width is compatible with the SeaQ 1-39-11-09-81-06. Milano Straps offers a comprehensive collection of artisanal 20 mm straps in alligator, NATO, rubber and vegetable-tanned calf, all designed to respect the visual proportions of the case and screw-down crown.

A premium leather strap (alligator or shell cordovan) typically lasts 2–4 years with regular use and proper maintenance. Saltwater exposure shortens lifespan; frequent freshwater rinsing is essential. Vegetable-tanned leather offers greater environmental resistance. An FKM rubber strap remains unaffected for 5–7 years even with frequent immersion, making it the most durable choice for those using the SeaQ primarily in water.
