What watches use 20mm straps?
The Rolex Submariner, Omega Seamaster 300M, Tudor Black Bay 58, IWC Pilot Mark XX, Longines HydroConquest, Tag Heuer Aquaracer, Seiko Prospex, and hundreds of other watches use 20mm straps. 20mm is the single most popular lug width in the watch industry — industry estimates suggest that over half of all 38mm–44mm case watches use 20mm spring bars. That means nearly every major category is represented: dive watches (Submariner, Seamaster 300M, SKX010), dress-sport hybrids (Longines Master, Tudor BB58), and everyday automatics (Seiko SRPD series). If you bought a mid-size watch from a mainstream brand in the last 30 years, there's a strong chance it's 20mm. To confirm, measure the gap between your lugs with calipers or check the manufacturer's specifications page — the lug width is always listed.
How do I know if my watch takes 20mm straps?
The most accurate method is to measure the gap between your watch's lugs with a digital caliper. Position the caliper tips at the inside edge of each lug, at the point where the spring bar sits. If the reading is 20mm, you need a 20mm strap. A standard millimeter ruler works too, but calipers give a cleaner reading. The second method is to look up your watch's reference number on the manufacturer's website or on a database like Watchbase.com or Chrono24 — lug width is always listed in the specifications. Third, check the underside of your existing strap: most quality straps print the width near the buckle end. If you're still unsure, any local watch shop can check for free in under a minute. A strap that's even 1mm off will sit visibly off-center in the lugs.
What are the cheapest 20mm watch straps on other sites?
The cheapest 20mm straps on other sites are G10 NATO nylon straps at $3–$6. These flat-woven nylon straps thread under the watch on a single long piece — simple, durable, and available in 50+ color combinations. Step up to $7–$15 for genuine or top-grain leather with quick-release spring bars — these feel substantially more premium at still a fraction of what brands like Delugs or Hirsch charge. FKM rubber dive straps run $8–$18 and deliver the feel of premium rubber at a fraction of the price. Milanese mesh in stainless steel runs $8–$20. Across all styles, 20mm has the widest selection on other sites of any lug width — typical savings are 80–90% versus retail strap brands. Paste any 20mm strap product URL into dupe.watch and we'll match it to the closest affordable options automatically.
Do I need quick-release spring bars for a 20mm strap?
Quick-release spring bars are optional but highly convenient. A standard spring bar requires a spring bar tool to compress the bar's ends — it takes about 60–90 seconds and carries a small risk of scratching the case. A quick-release strap has a small lever built into the spring bar itself: push it inward with your fingernail and the bar releases instantly. The whole swap takes under 5 seconds with no tools. Most quality other sites 20mm straps offer a quick-release version for $1–$2 more than the standard version. The minor tradeoff: quick-release mechanisms can occasionally feel slightly looser than a solid spring bar. If you plan to swap straps multiple times per week, quick-release is worth it. If you're setting a strap and leaving it, save the $2 and go with standard spring bars.
