Christopher Ward · C63 Sealander Chronograph
Strengths
Clear counters and easy bracelet adjustment are the strongest arguments here. The 13.9 mm thickness matters more than resemblance to famous chronographs.
Things to consider
The 13.9 mm thickness and 174 g bracelet-equipped weight call for a try-on. The checked EU page lists pre-order for mid-November 2026, rather than immediate dispatch.
IWC · Big Pilot’s Watch Perpetual Calendar TOP GUN Edition Mojave Desert
Strengths
The strongest attraction is the complex calendar paired with a matte desert palette. For a lover of large mechanical watches, 46.5 mm gives the displays room, but demands a suitable wrist.
Things to consider
Try it on before buying: the case measures 46.5 × 15.5 mm. Confirm the movement in the actual example; the original announcement and current IWC listing differ.
