Citizen Tsuyosa Automatic vs Seiko 5 Sports Field GMT SSK023

Buy the Seiko SSK023 if you want a GMT, 100m water resistance and a rugged field watch. Buy the Citizen Tsuyosa if you want a slimmer dress-sport watch with a sapphire crystal and a lighter feel on the wrist. The Seiko has the more useful movement and tougher water rating; the Citizen has the better crystal and cleaner proportions. Owners of both praise the finishing for the class, but the Seiko's Hardlex scratches more easily and its 13.6mm thickness sits tall, while the Citizen's 50m rating and lack of a screw-down crown limit it to desk and street duty.

• Choose the Citizen Tsuyosa if you want a slim, light automatic with a sapphire crystal for office and everyday dress wear.
• Choose the Seiko SSK023 if you travel or need a second time zone and want 100m water resistance in a field-watch case.
