Citizen’s Eco-Drive Proximity connected timepiece keeps its smart features running continuously without a battery thanks to solar power charging.
Its watch functions are top end as well, featuring a one second chronograph measuring up to 60 minutes, alarm, perpetual calendar, 12/24 hour time, dual time, power reserve indicator and light level power indicator.
The Proximity app activates the automatic date and time synchronisation and Link Loss, which allows you to locate your phone; and notification and call filtering that lets you manage alerts from selected contacts.
Incoming messages to a phone will trigger a vibration on the watch, plus the second hand sweeps to point at various icons on the dial ring that denote whether there is an incoming call, email, SMS, Facetime, a calendar event or social media alerts.
We particularly like the latest black steel edition, retailing for £429.
It is substantial, at 46mm across the case, but packs everything a watch lover and tech enthusiast would want into a piece that never needs to be charged.
