Details
Navy blue is the quiet alternative to black: just as versatile, but with more depth when the light hits it. On a stainless steel deployant clasp, this FKM rubber strap feels polished enough for the office and tough enough for the sea. Navy suits blue, black, white and grey dials and blends with blue or black bezels. It is the colour of tailoring and sailing alike, so it moves easily between a blazer and a weekend on the boat.

Made for 18 mm / 19 mm / 20 mm / 21 mm / 22 mm lugs
Straight ends on standard spring bars, 18 mm / 19 mm / 20 mm / 21 mm / 22 mm at the lugs. It fits any watch with that lug width; the models we had in mind are listed under Details.
Rubber made for every day
Soft, matte rubber that flexes with the wrist from the first day, with no break-in. It does not soak up sweat or sunscreen, so after a swim or a run you rinse it under the tap and it is dry in minutes.
Swapped in minutes, dispatched in 1–3 business days
The strap fits on standard spring bars, so the swap takes a couple of minutes with a spring-bar tool. If you do not own one, the Lugline spring-bar tool is $13.00, or any watchmaker will do it while you wait.
US shipping is $5.99 and free from $40. Orders are dispatched in 1–3 business days and typically arrive about 7 business days after dispatch. Unworn straps can be returned within 30 days.
