Lug width: 20mm

Watch Straps for the Christopher Ward C65

Christopher Ward C65 — all colorways

The Christopher Ward C65 is a vintage-inspired diver line that's become a strap-lover's favorite, thanks in part to its drilled lugs and quick-release hardware. Across the Trident, Dune, and GMT variants, the C65 takes a 20mm lug width, opening up the entire aftermarket of rubber, leather, sailcloth, and nylon. Christopher Ward's own straps are reasonably priced at $30–$90, but you can go lower. The C65's vintage character — domed crystal, retro dials, faux-aged lume on some models — pairs especially well with tropic rubber, distressed leather, and beads-of-rice bracelets. Because the case is moderate in size and thickness, thin and thick straps both work. Other sites carry 20mm FKM rubber, leather, sailcloth, and tropic straps starting at $6.

  • 02Christopher Ward fits quick-release spring bars to many of its straps and bracelets, so you can change straps tool-free; look for the same feature in aftermarket 20mm straps.
  • 03The C65's vintage styling pairs naturally with tropic rubber and aged-leather straps that play up the retro, sun-faded aesthetic.
  • 04For a heritage all-steel look, a 20mm beads-of-rice or flat-link bracelet suits the C65 better than a chunky modern Oyster.

Frequently asked questions

What lug width is the Christopher Ward C65?

The Christopher Ward C65 uses a 20mm lug width across its main variants, including the C65 Trident, C65 Dune, and C65 GMT (typically on 38–41mm cases). That means any 20mm strap fits between the lugs. Because 20mm is one of the most common sizes in watchmaking, you have an enormous selection of rubber, leather, nylon, and bracelet options. Most C65 models also have drilled lugs and quick-release spring bars, which makes the swap even easier than on watches that require working a tool between undrilled lugs.

Are the C65's drilled lugs useful for strap changes?

Very. Drilled lugs have holes in the outside of the lugs, so you can push the spring bar out from the exterior with a simple pin or the tip of a spring bar tool — far easier and lower-risk than levering from inside undrilled lugs. Combined with Christopher Ward's quick-release spring bars, the C65 is one of the most swap-friendly watches in its class. This is a big reason the C65 has a reputation as a 'strap monster' that owners endlessly customize.

What strap style suits the C65's vintage look?

The C65's retro design — domed crystal, vintage-toned dials, and aged lume on some models — pairs beautifully with strap styles that lean heritage. Tropic-style ribbed rubber is a period-correct dive look, distressed or oiled leather adds warmth and patina, and sailcloth gives sporty texture with a refined edge. For an all-metal vintage vibe, a beads-of-rice bracelet beats a modern sport bracelet. Christopher Ward's own straps cost $30–$90; comparable 20mm tropic, leather, and sailcloth from other sites starts around $6.

Can I fit a rubber strap to the C65 for diving or summer?

Yes. As a genuine diver, the C65 is well suited to a 20mm FKM or tropic rubber strap that handles water, sweat, and daily abuse. FKM rubber is the most durable and resists UV and chemicals, while tropic-style rubber adds vintage character with its ribbed pattern. Quick-release spring bars (standard on many C65 models) make swapping to rubber for the beach or pool effortless. Aftermarket 20mm FKM rubber from other sites starts around $8, so a dedicated summer strap costs very little.

Does an aftermarket bracelet fit the C65?

It can, but bracelet fit is the trickiest swap because the end links must match the C65's specific case shape. Christopher Ward sells bracelets sized exactly for each C65 case, which is the safest route for a perfect fit. If you go aftermarket, a 20mm beads-of-rice or flat-link bracelet with straight or generic curved end links will fit the lugs, though you may see small gaps where it meets the case. For most owners, the easy win is rubber, leather, and nylon straps, where the 20mm width and drilled lugs make swaps foolproof.
