Who should buy which.

The Promaster Skyhawk A-T Blue Dial (JY8078-52L): A pilot-watch fan who wants a world-time, alarm and chronograph tool that never needs a battery. Choose a plain three-hand watch if you want something slim and quiet. Choose the Skyhawk JY8146 if you prefer the darker dial.

The Zenshin Chrono Silver Dial (CA4610-85A): A buyer who wants a solar chronograph in titanium that works as an everyday watch. Choose a pilot ana-digi like the Skyhawk if you want world time and alarms, or a simple three-hand watch if you never time anything.

Before you order.

It is large and heavy for what it is. Citizen lists a 45 mm case and Watches of America lists 14 mm thickness, so it will not slip under a fitted cuff. The ana-digi dial is also busy, and learning the crown and pushers takes a read of the manual.

Citizen publishes a 42.5 mm width but no lug-to-lug or lug width, so check the fit on a wrist or a ruler before ordering. Watches of America lists the case as 11 mm thick.
