- Weekend warriors — 80-hour power reserve means it survives two days off the wrist
- Those who prioritize scratch resistance — sapphire crystal

Rado Captain Cook High-Tech Ceramic
- Ceramic is brittle — drops/sharp impacts can crack the case. Full case replacement, not repair.
- 15.4mm thickness — chunky; won't slide under dress cuffs.
- Skeleton dial is polarizing — many prefer a traditional solid dial.
- ETA C07 base movement at this price — you're paying for the ceramic, not the movement.
Rado True Square Automatic
- Ceramic brittleness — virtually scratchproof but can crack/shatter under hard impacts. WatchUSeek Rado threads document multiple owner reports of ceramic cracking from drops that would only scratch steel cases. Insurance is recommended.
- Square format polarising — distinctive and modernist, but not for buyers who want traditional round cases.
- 50m water resistance — dress watch only; not for swimming sports or hard activity.
- Proprietary endlinks — severely limits aftermarket strap options.
