The Christopher Ward C65 Divetimer Limited Edition 41mm represents a genuinely functional piece of dive equipment through manually-wound construction limited to 150 pieces that sold out within 24 hours of its 1 July 2021 announcement. The distinctive colourful dial integrates decompression tables directly into the time display, providing scales for 25m, 30m, 35m, and 40m depths that indicate both the no-decompression time limit and the required decompression stop duration should a dive extend beyond that threshold.

At 41mm with 11.5mm thickness through 316L stainless steel construction, this provides elegant diving watch proportions whilst the decompression table dial creates unmistakable visual character rooted in genuine practical function rather than aesthetic decision. Following the arc for a chosen depth reveals first the safe no-stop limit and then the required pause time, so a 45-minute dive at 40m reads as requiring a 60-minute decompression stop.

The Sellita SW210 manually-wound movement delivers clean mechanical operation through hand-winding that eliminates rotor bulk whilst maintaining the slim 11.5mm profile. The manual winding also creates a direct connection between diver and instrument that suits the C65 Divetimer’s purposeful character.

The 150m water resistance covers recreational diving applications whilst the standard Mk2 Trident stainless steel bracelet provides robust everyday wear. The 22mm lug width ensures broad strap compatibility for those who prefer to wear it on rubber or neoprene when diving. 150 pieces, sold out in under a day, with a decompression dial that actually works underwater. The C65 Divetimer is the sort of limited edition that justifies the designation.
