Citizen really knows how to impress people with this smooth hands =) Citizen Eco-Drive Technology – No Need For A Battery Anymore Notice how beautiful the hands moves and glides on the dial when operating it. Let’s have a look at how these functions work.Ĭheck out this useful video on how to use the watch’s various functions. It’s like a smartwatch from Samsung or Apple but with the gorgeous design of an actual watch. There is no need for the owner to even set the time/day/date or anything. What I really like is how these functions helped to make the watch truly independent and can work on its own. There are a few things that is not there that I would love to have such as compass and watch light but then you can’t really have everything right? Here is the list of functions that the Citizen Eco-Drive Perpetual Chronograph AT4010-50E Watch has:ġ- Solar powered by Citizen’s Eco-Drive technology

The watch is truly a technical achievement. The reason why titanium is pricier than steel is due to the scarcity and difficulty in molding and welding the element.įor more info on titanium, you can read more on and. Titanium has a matte finish while stainless steel is more shiny or polished. It’s also an inert element and it’s hypoallergenic property is a great option to those that have allergy to steel.Ī big difference with stainless steel is the appearance. Not only that, titanium also is highly resistant to corrosion such as sea water and your own sweat. Using titanium as watch material will make the Citizen Eco-Drive Perpetual Chronograph AT4010-50E Watch much lighter, just about 100 g. This gives it a better strength to weight ratio than steel. The reason? Titanium has almost the same strength of steel, but it has almost half of steel’s density or weight. Titanium is an element that is widely used in aerospace industry. The material used for the case and bracelet of the Citizen Eco-Drive Perpetual Chronograph AT4010-50E Watch is titanium which is a premium material for watch making. In my opinion, a 22 mm lug width is enough for watch with this size. The lug width is 24 mm which actually make the watch looks larger. Most quartz watch has much thinner profile but this is not your ordinary quartz watch though, so those extra milimeters are totally justified. The watch is 42 mm in diameter and is not too big for most guy’s wrist. The inner circle of the dial is textured and contains the solar panel of the watch. The use of reflecting metals such as the marker linings, subdials and outer edge of dial is a very nice touch. But surprisingly the dial – as congested as it may be – is very well designed.Ĭitizen has tried to make the watch as symmetry as they could. You can see the 3 subdials on the face that have different functions to play (more on that later). Sure there is a lot going on the 42 mm diameter watch but that’s what to be expected from a chronograph. The design of the Citizen Eco-Drive Perpetual Chronograph AT4010-50E Watch is quite nice to look at. Nice Design With Titanium Case For A Very Light Wrist Watch In addition, with its atomic clock syncing every day, it can be said to be as accurate as an atomic clock!

Although it’s a quartz wrist watch, it has a huge amount of functions that excite the techie spirit in me. But this Citizen Eco-Drive Perpetual Chronograph AT4010-50E really blows my mind. I have always been an automatic watch guy and don’t really like quartz watch in general.
