Review: Fantastic watch, and a real bargain! - I love Grand Seiko, and Citizen Chronomaster, but those watches are not in my budget. I never thought about Casio until reading reviews about this watch. I am glad I decided to give Casio a try, as this JDM watch is fantastic. Great design and finishing on the bracelet, watch face, and case. The comments by others about the difficulty of taking out links of the bracelet are valid ones. If you don’t have the proper tools and experience, do yourself a favor and take it to a quality jeweler that works on watches, and tell them that the watch has a bracelet with the pin and sleeve type links. The watch is easy to set up, and the second hand hits the marks on the watch face exactly. After the time synchs with the atomic clock, it is amazing to compare with the time on your cell phone, and see the minute change on your phone at the same time as the second hand on your watch hits the twelve o’clock position. It is amazing to set the time zone to Tokyo and watch tha watch hands and date change like magic. The titanium bracelet and cas are so light weight that you don’t even notice that you are wearing a watch. A great bargain on a top quality watch. The brand may not have the same status as some, but the watch itself lacks nothing compared to the others. Update: After 3 months, This watch has become my daily watch. My dozen or so other watches have been sidelined, and I am considering selling most of them. I often wear another dressier watch in the evening, but this watch is so versatile and comfortable, there is little reason to wear anything else. It has missed synchronizing only one night in 3 months, and that is when we were staying overnight in an RV, although it worked the other nights in the camper. I have picked up a few minor scratches and tiny scuffs, but the finish is much harder to scratch than stainless steel or regular titanium. For traveling, this is the only watch I bother bringing. For a one watch guy, this could be the one for you. This is a little larger diameter than I usually wear, even with a 7.5” wrist, but is is still modest in size, and with the light weight, you don’t even notice you are wearing a watch.
Review: Classic Form meets Function - There are a number of things that attracted me to this particular Oceanus watch. The 2 main reasons are that overall the watch is a smaller sized watch that fits my wrist well and the dial is uncluttered and very readable. While higher end watches in the Oceanus range may have additional features and use higher end components, I find the models with multiple dials just too busy. The S100 has a very clean dial which gives it a "Classic" look that is unlikely to date in the years to come. Like other watches in the Oceanus range, it has tech which places the watch as one of the most accurate watches that you can buy. Yes - it is a quartz watch, but with Atomic time synchronization which means the watch is accurate to the second. Mine synchs to the US Atomic signal in Colorado every night without a hitch. The additional cost you are paying over a simple $20 quartz watch is evident in the titanium case and bracelet which are beautifully finished, the double-dome Sapphire crystal, the tough G-Shock movement and the fact it is Solar powered. This watch is also built for world travel. Flying to another time-zone? Pull out the crown, move the second hand to point to the new time zone on the inner bezel and voila! The watch adjusts the hour hand to the correct zone automatically. On receipt of the watch from Japan (within 3 days of purchase), I needed to size the bracelet by removing several links. The bracelet does have half size links which make it easy to size correctly, but I do recommend buying one of the bracelet adjustment kits available on desertcart to help with this. I have had the S100 for several weeks now and it is very light-weight and comfortable on the wrist. The hands are very accurately aligned (The second and minute hands have dead on alignment). Watches in this price range often suffer from slight hand mis-alignments. Of note - the Oceanus has a self alignment system built in, that you can run to re-align the hands if for some reason the hands are jarred out of alignment. The only down-side that I can see to this watch is that it is a JDM and does not have the regular warranty you would get from a domestic model. Also the longevity and ease in which i will be able to replace the Solar power pack (when it eventually dies) is an unknown at this time. Other than these minor concerns, there are few negatives to balance against a beautifully designed watch whose form and function are outstanding. ***4 Year Update*** This watch has been in daily use for close to 4 years now. Additional impressions and takeaways: - Incredible lightness and comfort - Sapphire Crystal has held up very well. No visible scratches after 4 years use - Titanium bezel and the watchband clasp have tiny fine line scratches. But the rest of the titanium case and strap are like new with no signs of wear - World Time synch has been very consistent with maybe 1 or 2 misses of the nightly synch each month. - Trouble free over long term with brilliant accuracy Overall - This purchase was one of the best value for money buys that I have ever made. Nothing but praise for Casio in putting out this wonderful and stylish watch. A true GEM!
