Reviews
I like the watch very much and wear it everyday. It replaced my AP, Blancpain, Rolex, and Omega and becomes my daily watch now. It is low-profile, shinny, lightweight. The best part: I will never need to adjust time!
A perfect minimalist watch
I have had this watch since day #1 (ordered on 10/03/2019). In 2 years it lost a total of appr. 3 seconds (1 sec in year #1 and 2 secs in year #2). It is consistently losing time at a microscopic rate. I guess, the extra 1 second I lost is not worthy for any complaints. I can only describe every aspect of it in superlative terms. Do I recommend it? Only for perfectionists.
A Bargain
This was the most expensive watch I have ever purchased -- 4 time more expensive than the most expensive watch I have owned. I love it. First, it is as accurate as claimed. Unlike my mechanical and quartz watches, it does not need any correction on a daily or weekly basis. The watch is elegant -- simple but beautiful as is the very different from standard watch band. I wear this watch daily; except for rigorous excursions like sailing. I am a Vermont elder male who would recommend this watch to anyone who cares about knowing the precise time.

An Engineering, Design & Craftsmanship Masterpiece
The account of John Harrison's efforts to produce the compact H4 in 1759 is one of the greatest in horology. Mr. Harrison was credited with accuracy of one second per month, an astounding characteristic surpassing even today's "superlative chronometers". Citizen joins Mr. Harrison in a feat of unrivaled design, the autonomous 0100 movement, with record-breaking performance. Everything about this is perfect for me: the name "Citizen", for I am proud to be a citizen of a republic, not the subject of a crown or a monarchy. The dial and furniture beautiful, but not ostentatious. The bracelet of special titanium, which will remain untarnished by the environment perpetually. And of course, the accuracy. Quite simply, the best accuracy. This is an engineering, design & craftsmanship masterpiece. I cannot think of any other piece on Planet Earth for which I would trade. I feel blessed and very fortunate to be one of the few to own one.
Near Perfection
This is a beautiful watch, and it performs exactly as advertised.
Elegant and brilliant designed watch.
Feel so lucky to be able to get this watch because so many collectors think this watch is over priced because of the brand. I think not. Citizen has packed this watch with their greatest innovation in a smart and elegant design. The watch is more beautiful than the look in the picture. The watch face looks simple and humble yet modern and sharp, truly reflecting the company and the culture of Japan. I love the fact that there is no date. Imagining with eco-drive tech. and +\- 1 sec per year, you don’t even need to adjust time in your lifetime. When I wear this watch, I feel like wearing a beautiful piece of art. People are complaining about the price, yet they are willing to pay an over-priced European watch they can’t even read the time sometime. I think that’s a brand bias. I hope Citizen will keep very limited production on this watch to make it a special collective item. Personally, I think this watch is way better design than PP, AP and a lot of other brand names out there.
A candidate for "One and Only" watch
The Caliber 0100 represents the greatest achievement in accuracy in all of horology in the past 300 years. The Caliber 0100 is the most accurate watch ever made. As a lover of horology I gave it the most serious consideration. It is an amazing piece. The movement speaks for itself. It is very likely that the Caliber 0100 is the only watch I will ever own that will not need to be set to a reference time for several years. Only the corrections for daylight savings time and time zones. The case and bracelet are hand finished with well defined facets and angles on the level with the highest level of hand finished horology pieces. The dial and dial furniture is immaculate. The layering process used on the dial has achieved the truest black I have yet seen on any dial, there is hardly a hint of blue. This titanium bracelet version of the Caliber 0100 is one of the best pieces ever made. I think it represents a reasonable candidate for a one and only watch. This puts it in some rarefied air with a select few historically great pieces in horology.
Great detailed design with unmatched accuracy.
In the November 2019 this watch arrived in the US stores. After making reservation a few months ago I finally bought it. This titanium watch is very light weight and with very nice designed bracelet it is extremely comfortable to wear. The outside metal finish and overall look of the watch is very good. Watch comes adjusted to local time zone and after inspected it for its accuracy by using atomic clock standard via radio waves, its accuracy was perfect. For people who like state of the art, technological marvel of accuracy, this watch is a must!
