Cooper Watches MWC "Depthmaster" 100atm / 3,280ft / 1000m Water Resistant Military Divers Watch features a 24mm strap, wider than typically seen on similar watches. Some online criticism exists regarding the brand's claims of being a military contractor and Swiss manufacturing. Overall, owners acknowledge the Cooper Watches MWC "Depthmaster" 100atm / 3,280ft / 1000m Water Resistant Military Divers Watch as a robust military diver, with the wider strap being a notable feature.
Owners widely praise the IWC Schaffhausen IWC Aquatimer Chronograph as an underappreciated, overbuilt tool watch prioritizing engineering and reliability, with its Valjoux-derived movement offering durability and its chronograph pushers providing mechanical feedback. Reviewers and owners consistently flag its impeccable finishing, captivating appearance, dial depth, and excellent lume, with one owner noting its comfortable wearability despite its size and thickness. Some owners find the chronograph variant chunky at 17mm, and the welded lugs limit strap options to OEM choices or require specific modifications for third-party straps. One owner notes the watch's 120m water resistance, attributing the reduction from the non-chrono version to non-screw-down pushers. Overall, owners rate the IWC Schaffhausen IWC Aquatimer Chronograph highly for its robust build quality and functional design at the price.
