I was debating on purchasing a used Citizen 2100 on ebay with the mineral crystal but when I found out the Citizen was relaunching the 2100 with an anti-reflective sapphire crystal, I had to have it. The 2100 is a classic design that wears very well even though it is a 44mm diameter watch. It's not too top heavy and weighs in at only 124 grms with 2 links removed. I suggest taking advantage of the free sizing because the pin and collar link system is not for the novice. The 2100 is a hand-assembled solar-powered mechanical-quartz movement which means it always has the correct time that never needs winding, and the second had sweeps when the mechanical chronograph is engaged. In my opinion, this is the perfect blend of technology, design, and beauty. Great job Citizen always a cut above.
Ordered this direct from Citizen and had it in hand within three days! I own four citizen watches and this implementation is by far the best, most functional, easy-to-read date, and I just love it. The timekeeping as measured and compared with a GPS watch and Atomic clock on line regulation is spot on -- not a fraction of a second off, after several weeks use. This is now my go-to everyday watch. PERFECT!
I bought in San Martin !!Since 2007"still working"
I have a previous generation Calibre Titanium 2100, purchased in 2008. It has performed beautifully, despite 13 years of daily wear in all kinds of activities. At this point it needs servicing and some repair and I expect I will buy a replacement in due course - but I have been very happy with the quality, style, function and performance of the Calibre 2100, and while I haven't made a decision on a new watch, Citizen is at the top of my list. The Eco-Drive system is an important attribute; not having to replace batteries is a significant convenience.
I bought this watch almost 20 years ago in it's original production. I've worn it almost every day since.This watch keeps perfect time and I only have to set it twice a year, Daylight savings time and back to normal time. If I didn't already have this watch, I'd probably buy it !
