Citizen JY8078-01L Sky Eco-Drive 45.4mm Blue Leather Men's Watch

Radio-controlled watch, sapphire crystal: the Citizen JY8078-01L

Overview

The Eco-Drive technology is featured in the Promaster Sky range: the JY8078-01L charges under any light source. On the blue dial, Arabic numerals and indices mark the hours. Promaster Sky brings together Citizen's aviation-style models. 45.4 mm in diameter, a stainless steel case and a leather strap make up the size. It is radio-controlled: the time is reset using a radio signal.

Case

The JY8078-01L case is made of stainless steel; it measures 45.4 mm in diameter and 14.4 mm thick. Water resistance is 20 ATM, or 200 m: the watch is suitable for long-distance swimming and free diving, without claiming to be suitable for scuba diving. The dial is fitted with a sapphire crystal, and a fixed bezel secures the strap.

Movement

The watch is powered by the U680-08A caliber, an Eco-Drive movement whose energy comes entirely from the light captured by the dial. The charge level can be read on a power reserve indicator, and a low charge warning alerts you when the watch is running low. When fully charged, it retains approximately 3.5 years of battery life without any light. In addition to the time, the dial also displays the full date digitally. The watch also features a 24-hour display, an alarm, a backlit dial, a chronograph and shock detection.

Strap

The leather strap has a 22 mm lug width. The strap is 220 mm long and the whole watch weighs 111 g. It comes with a 2-year warranty.

Supplied with: Storage box, presentation pad, user manual.
