LINEAGE(リニエージ)Casio] Lineage Radio Solar LCW-M100TSE-1A2JF Men's Silver

"Best watch ever" as another reviewer has said. Keeps accurate time and date thanks to radio time sync, solar power, easy to read, right size for small wrists, swappable band and lightweight. A few bonus functions like alarms, timer and stopwatch for those who need them. The only surprise is that they are not more popular. It should be a best selling watch.

There's no such thing as the best watch in the world, but Ben's Watch Club channel on Youtube used the headline in quotes above for a video about the M100TSE-1AER.There are two :Casio Lineage LCW-M100TSE-1AER (with a grey classy non numbered dial)Casio Lineage LCW-M100TSE-1A2JF (numbered darker grey dial resembling a 'field watch'. This one here)(other than the dial color and design, they are absolutely identical.Features:Titanium band !Titanium caseEasy adjust band link tool.Solar powered quartz movement.Radio wave automatic time setting daily.You never charge or change batteries or set the time, that's done by the watch all by itself !The easy band link tool is amazing. 10 seconds tops to remove a link or add one. Instead of several minutes skillfully using tools. Only one tool that a moron can't mess up or scratch the watch.You can see the two watches here on Amazon. As I write this both are available to ship from America in a couple days from Amazon. This is important because these watches were meant by Casio to be sold in Japan, not America. Therefore, most American watch stores won't carry these watches.The module number is 5161. Casio English language user manuals are listed by module numbers. 5161 is for these two watches. Module numbers are always engraved on the back of Casio Watches.This watch will try each day to receive radio signals and sync the time to the atomic clock in Fort Collins, Colorado. Or to other atomic clocks around the world (I think 1 in England, 1 in Germany, 1 in Japan, and 1 in China.The time it will try and sync is 5 times every day: Midnight, 1 AM, 2 AM, 3 AM, 4 AM. If it syncs then the remaining attempts that day will not happen, because it is already is synched for that day.I live 875 miles direct line from Fort Collins. At night while I wear the watch sleeping it has synched every single day. People say that sometimes during poor radio reception days, such as a solar storm, it will not synch. But you can always set the time manually. Also at any time you want, you can force the watch to try and radio synch, instead of manually sync. This allows you to move around the house and find the spot with best radio reception, such as on a window sill.I have owned this watch less than a week, and it synced at night on my wrist in bed every night.Functions: Time, 24 hour time zone time, radio sync, alarm (5 alarms), stop watch (count up), Timer (count down). For many years now, I use a stop watch to count up time, many times each day of the year. And it is easy to do with this watch, and easy to read the numbers on the timer.Weights that I measured:This Casio Lineage watch with titanium band: 2.26 ounces.Seiko SKX009 divers watch with a nylon NATO strap: 3.75 ounces. (Would weigh more with a stainless steel expansion band, maybe 4.5 ounces)?So, the weight savings is about half. A stainless steel Casio diver on a stainless steel band would weigh just about double this titanium watch on its titanium band.I really love this watch, and it is the most comfortable watch I ever put on my arm!

The move to quartz was a leap after my Seiko 5 called it quits after 20 years... However it is nice to have all the extra features this watch provides!It is comfortable, very easy to read (the lume is indeed weak as reported by others), and very VERY accurate. I swapped the titanium bracelet (which could easily be adjusted down to fit my 6 1/4" wrist) for a 20mm nylon one. At this price, the watch is a super value - shipping was reasonably fast.Thank you Ichigo Ichie Japan (seller). This may very well be the last watch I ever purchase!

Despite the fact that the seller indicated not entirely correct data in the product description and does not answer questions, I decided to purchase them because I had been waiting for the availability of this particular model (with Arabic numerals) on Amazon for a very long time.With titanium case and sapphire crystal.A description of this model can be found on the manufacturer's website.

Not one word in the instructions in a language I can understand...just hieroglyphics..online tutorials are no help either...I followed instructions of Youtube about how to set day and date..I followed the instructions step by step..over and over for over 4 hours..could not get my watch to do what the instructions said..so..I gave up and have returned the watch for a refund.

This watch is one of the beautiful Casio Lineage series of watches. Titanium body. Sapphire crystal.Received the WWV atomic time update every night. It has a solar rechargeable battery.I love this watch. I wear it almost daily.

So far it has been very positive, it has a lot of features in a field dress style, though 50m/5 bar water resist, it can give you world time, 5 alarms, timer, stopwatch, LED & low level lume, all titanium case & strap, battery indicator, safety clasp. As lightweight as many resin watches at 73grams, with a sapphire crystal. I personally wouldn't go swimming or bathing with it, but it should survive the odd rain shower. I think these are an all around kickass product!.

Easy link setup, easy setup. Needs charging in full sun after purchase. Setup is OK from english manual. Good price for titanium sapphire solar radio watch. Don't notice I'm wearing it.
