CITIZEN CA4691-59L SUPER TITANIUM ECO-DRIVE CHRONOGRAPH MEN WATCH

The Citizen CA4691-59L is the blue Zenshin Senkei chronograph — Senkei being the Japanese for "clear lines", which is the brief the whole watch is built to. The case is a multi-sided design that integrates directly into a three-row bracelet, all in Super Titanium: Citizen states it is 40% lighter and five times harder than stainless steel, and it is scratch- and rust-resistant.

The dial is textured blue with a fine grid-like pattern, applied luminous indexes and three concentric-grained sub-dials. Blue is the version where the texture shows best — the pattern catches light across a coloured surface in a way it cannot on white, so the dial shifts between deeper and brighter tones as the wrist moves. The running-seconds register above 6 o'clock is finished in a contrasting tone to the two chronograph totalisers at 3 and 9, so you can tell at a glance which sub-dial is doing what.

A deeply knurled crown and brushed finishing throughout complete it. Inside, Eco-Drive Calibre B620 runs on any light with a nine-month reserve and accuracy of about ±15 seconds a month. The chronograph measures to 1/5 second up to 60 minutes, with 12/24-hour time and a date window at 4:30. Sapphire crystal, screw-in Super Titanium caseback, 100-metre water resistance, 41mm across and 11.7mm thick.

Why You'll Love It

• Super Titanium is 40% lighter than stainless steel. On a 41mm chronograph with a full integrated bracelet — the heaviest configuration in watchmaking — that difference is obvious within an hour and never stops being the reason you reach for it.
• It is also five times harder than stainless steel and scratch- and rust-resistant, so unlike ordinary titanium it holds its finish rather than marking on the first desk edge.
• Blue is where the grid texture earns its place. On a coloured dial the pattern catches light and shifts tone across the surface; on a plain white face the same texture is far quieter.
• The contrasting sub-seconds register is a genuinely thoughtful piece of design. On most three-register chronographs all the sub-dials look alike and you have to think about which is which; here the distinction is instant.
• A chronograph that never needs a battery. Stopwatch use is what flattens a conventional quartz cell fastest, so most owners quietly stop using it — with Eco-Drive there is no reason to.
• Nine months of reserve from a full charge, and accuracy of around 15 seconds a month. Set it and forget it.
• The multi-sided bezel and deeply knurled crown are the details that stop it looking generic in profile — you get definition and grip rather than a smooth slab.
• Titanium is hypoallergenic, which matters on a chronograph that sits against the skin all day.

Key Features

• Super Titanium case, bezel and bracelet with Duratect — Citizen's proprietary titanium alloy with surface hardening: 40% lighter and five times harder than stainless steel, scratch-resistant, rust-resistant and hypoallergenic.

• Chronograph to 1/5 second, up to 60 minutes — a stopwatch with genuine resolution, displayed across the 3 and 9 o'clock totalisers.
• Contrasting sub-seconds register — the running-seconds sub-dial above 6 o'clock is finished in a contrasting tone so it reads clearly apart from the chronograph totalisers.
• Textured blue dial with grid pattern — with applied luminous indexes and three concentric-grained sub-dials.
• 12/24-hour time and date at 4:30 — a second time reading on its own register, and a date window set between 4 and 5 o'clock.
• Multi-sided bezel and deeply knurled crown — the design signature of the Senkei line, with brushed finishing throughout.
