Extra Long Watch Bands
A standard watch strap is cut to fit a wrist of approximately 6.5 to 8 inches circumference. For wrists larger than this — and a significant number of men have wrists of 8 inches or more — a standard strap runs out of adjustment holes before it reaches a comfortable position. The buckle lands at the last hole, the tail barely threads through the keeper, and the strap sits too tight or refuses to close at all. It is a problem with a simple solution: an extra long strap cut to a longer overall length with proportionally extended hole spacing.
CNS Watch Bands extra long watch bands are available in nylon and full-grain calfskin leather — extended length versions of the standard collection cuts, designed to fit wrists from approximately 8 to 9.5 inches circumference without the tail running out. Available at 18mm, 20mm, 22mm, and 24mm lug widths. For wrists on the smaller end, see the short watch bands collection.
Who Needs an Extra Long Watch Band
Men with larger wrists — the primary audience. Standard strap lengths are designed around a median male wrist of approximately 7 to 7.5 inches. Wrists of 8 inches or above regularly run out of adjustment on standard straps. The problem is most visible on nylon single-pass straps where the excess tail is supposed to thread through a keeper — if the strap is too short, the tail barely reaches. On leather straps, the problem is simpler: the buckle either does not close or closes at the very last hole.
Divers wearing over a wetsuit — a dive watch worn over a wetsuit sleeve adds significant circumference. Even a wrist that fits a standard strap easily can run out of adjustment when wearing a 3mm or 5mm wetsuit. Extra long nylon single-pass straps and the Barracuda velcro diver strap are the standard solutions for this — but an extra long cut provides additional margin for thicker suits and multiple layered sleeves.
Pilots and outdoor professionals wearing over sleeves — flight suits, base layers, and thermal sleeves all add wrist circumference. The standard military nylon single-pass strap is already cut longer than a standard leather strap for this reason. An extra long cut extends this further for wearers with both large wrists and thick sleeve layers.
Collectors with large wrists who want the full strap rotation — buyers with larger wrists should not have to restrict their strap choices to the handful of products that happen to fit. The extra long range extends the full material and style spectrum — nylon, leather, suede — to wrists that standard cuts cannot serve.
Extra Long Nylon Watch Bands
Single-pass ballistic nylon in extended length — the most practical extra long strap for daily and active use. The military nylon single-pass construction provides spring bar security backup as standard, water resistance, and the same solid buckle as the standard Original range. Available in the full solid colour and regimental stripe palette of the Original collection.
For collectors who want the full nylon range in extra long, the following styles translate directly to extended length:
- Original nylon — flat ballistic nylon, solid buckle, the baseline extra long nylon option
- Ribbed nylon — corded texture, exclusive CNS colourways including mustard yellow, in extended length
- RAF style — single-pass with fabric keeper, lower hardware profile, in extended length
- Z strap — heavy-duty single-pass with oval hardware, already cut long as standard — the most naturally large-wrist-appropriate strap in the CNS range at 22mm and 24mm
Extra Long Leather Watch Bands
Full-grain calfskin in extended length — the same premium leather as the standard collection, cut longer with hole spacing adjusted proportionally throughout the adjustment range. Extra long leather straps provide the same patina development, the same formal character, and the same range of constructions as the standard leather range — extended to fit wrists that standard cuts cannot reach.
Available constructions in extra long leather:
- Classic flat calfskin — smooth and pebble-grain in black, brown, and the full colour range
- Padded calfskin — the most substantial construction for larger sport and pilot watches
- Vintage two-stitch — period-correct two-stitch construction in cognac, tan, and dark brown
- Suede — the softest and most casual extra long leather option
Extra long leather straps suit the same occasions as standard leather — formal and smart-casual wear, dress and dress-sport watches — without the adjustment compromise that makes standard lengths uncomfortable or unwearable on larger wrists.
How to Know if You Need an Extra Long Strap
Measure your wrist — wrap a flexible tape or a strip of paper around your wrist just above the wrist bone. If the circumference is:
- Under 6.5 inches — you likely need a short strap
- 6.5 to 8 inches — a standard length strap will fit correctly
- Over 8 inches — an extra long strap will give you comfortable adjustment with tail to spare
Check your current strap — if your current strap buckles on the last or second-to-last hole and you have almost no tail left after the buckle, you are on a strap that is too short. An extra long cut will give you three to four additional holes of adjustment range and a correctly positioned buckle at the correct point.
Check your tail length — on a nylon single-pass strap, the long tail should be long enough to thread through both keeper rings with several centimetres to spare. If the tail barely reaches the second keeper, the strap is too short.
What Watches Suit Extra Long Straps
Extra long straps fit any watch at the correct lug width — the extended length affects fit on the wrist, not compatibility with the watch case. The most common pairings:
Large sport and dive watches at 22mm — Tudor Pelagos, IWC Pilot's Watch, Marathon GSAR. Larger watches are disproportionately worn by wearers with larger wrists. The 22mm extra long nylon is the single most practically useful extra long option in the range.
Dive watches worn over a wetsuit at 20mm and 22mm — Omega Seamaster, Rolex Submariner, Tudor Black Bay. Extra long nylon provides the additional length needed to close over a 3–5mm wetsuit sleeve without running out of adjustment.
Pilot watches at 22mm and 24mm — IWC Big Pilot, Panerai Luminor. These are large watches on large wrists and the extra long cut is often essential rather than optional. Padded extra long leather and extra long nylon are both appropriate.
Everyday wear at 20mm — any watch on a larger wrist. The 20mm extra long in classic black leather or military nylon is the most versatile large-wrist everyday option.

Extra Long vs Adjustable Straps — Which is Right?
Two solutions exist for buyers who fall at the long end of the adjustment range:
Extra long straps — a longer overall cut with proportionally spaced holes. The strap looks and functions identically to a standard strap; it is simply longer. The correct solution for wrists over 8 inches where the extra length is structurally needed.
Adjustable straps — standard length but with a micro-adjust buckle providing additional pin positions between the main holes. The correct solution for wrists that fall between two standard holes on a standard strap — not for wrists over 8 inches where the standard length itself is insufficient.
For wrists at the boundary (approximately 7.75 to 8.25 inches), either option may work. For wrists clearly over 8 inches, the extra long cut is the correct solution.
Frequently Asked Questions
How long is an extra long watch strap? A standard watch strap is typically cut to approximately 120mm (long piece) and 75mm (short piece). An extra long strap is typically cut to approximately 130mm and 85mm — adding 10mm to each piece, which is enough to provide three to four additional hole positions and comfortable tail clearance on wrists up to approximately 9.5 inches circumference.
What wrist size needs an extra long strap? Wrists over approximately 8 inches circumference will generally benefit from an extra long strap. Between 7.75 and 8.25 inches is the boundary zone — some buyers in this range will fit comfortably on a standard strap, others will find an extra long more comfortable. If your current strap buckles on the last hole, order extra long.
Are extra long straps available in leather? Yes. CNS extra long straps are available in full-grain calfskin across classic flat, padded, vintage two-stitch, and suede constructions.
Do extra long nylon straps fit over a wetsuit? Yes — this is one of the primary applications. An extra long single-pass nylon strap provides sufficient length to close over a 3–5mm wetsuit sleeve even on a larger wrist. For thicker suits or layered sleeves, the Barracuda velcro diver strap provides even more adjustment range through its hook-and-loop closure.
What is the difference between extra long and the short watch bands? Short watch bands are cut shorter than standard for wrists under approximately 6.5 inches — eliminating excess tail on smaller wrists. Extra long watch bands are cut longer than standard for wrists over approximately 8 inches — providing the additional length that standard straps cannot reach. Both are sized by wrist circumference rather than lug width.
