Casio PRW3500 Series | Pro Trek | 100M WR | Compass | Alt/Baro-Thermo | Tough Solar Power | Atomic Timekeeping | 1-100 SEC Stopwatch | Countdown Timer | World Time

Accurate time keeping, barometer and sun rise and set times proved useful on recent journey. Altitude once set is accurate and calibration during the day from known heights is easy to do. The compass also performs well. All in all a super watch and Time can be seen in poor light before its necessary to use the internal light.

Bought this as a gift and must say my partner loves it . Not sure ab8 the functions as he was the one that done all the research on these types of watches, but he loves it .

Comfortable easy to read.

you would have though that as casio has come out with a new watch.my casio pro trek prw 3510 8cr came today.i was not imprested.its the same features as 3500.there are no new features on the 3510.all casio have done is change the look of the watch.given the prw 3510 a new look.the watch face is to small so its hard to see the time.the display.there is a video about the 3510.it makes out that you want to bye it. dont bother.save your money.its not worth paying £222.the watch is over price.£160.is the right price for the 3510 8cr.mr

Unable to read the display on the watch as it is too dark, and having a lot of problems even getting UPS to accept the package back due to their degraded returns drop off point system.

Does what it says on the tin,good quality

Genuine watch if this will go on sale again i will purchase again

見た目も格好良いし、多機能のソーラー電波なので楽しさ満載。海外にも人気があるようで、今では買った当初の倍額に…。

Excelente reloj, cumplió con todas mis expectativas, el material se siente de bastante calidad, llevo dos semanas utilizandolo diariamente y no se siente tan grande como parece. Lo he probado en un par de rutas haciendo senderismo y es muy práctico, los sensores de altitud y barómetro funcionan bastante bien.

Gefallen hat: - leicht bedienbare Stopuhr, - leicht startbare Barometerfunktion mit Kurven-Anzeige (Wettertendenz erkennbar), - leicht startbarer Kompaß, - ergonomische Bedien-Knöpfe - gutes Aussehen (das Kunststoffgehäuse sieht nicht nach "Plastik" aus)! - endlich keine Sommer-/Winterzeitumstellung mehr, kein Nachstellen der Uhr (wg. Atomzeit) und kein Batteriewechsel mehr alle paar Jahre (wg. Solarladung mit Akku)! Weniger angenehm ist das Silikonarmband, da bin ich auf ein angenehm zu tragendes Nylonarmband umgestiegen. Zum Schwimmen ist ein Nylongewebeband aber evtl. weniger sinnvoll (trocknet sicher schlecht durch), da sollte man das Original-Silikon-Armband behalten...

So far, this watch is amazing. It looks bad-astronaut with the full-size look, military vibe, and negative display. The features exceed what I ever imagined I would want in a watch, but now that I have them, they are fun to experiment with and I really enjoy knowing they're there. MUST HAVES: - The solar power and multiband 6 (atomic sync) are must-haves, for me. I don't want to have to babysit and potty train my watch. I don't serve my watch; my watch serves me. - I wanted a watch that could display the time while the stopwatch and/or timer was in use. - I wanted big digits so I wouldn't need glasses to check the time. - I wanted digital -- while I love the elegant appearance of analog watches, I can't get over the fact that the hands obstruct vital parts of the watch every hour. That's unforgivable to me, hence my requirement for digital. - I don't want my watch to make me look like a dork. The ProTrek checks all the boxes. DISPLAY: The readout is extremely easy to read. Negative displays have a negative reputation as they are often difficult to read but this one is clear and crisp at all angles. Bright sunlight does NOT wash-out the display, it actually makes it more readable. In dim lighting it is harder to read than a positive display but it is readable, and besides, the backlight (and auto-backlight) are there for a reason. Additionally, given the large nature of the watch, I felt that the negative display suited it better. The dark appearance makes it easier to get away with having such a beefy watch. (I use the same strategy for my size 15 shoes: the darker the better.) BEEP: The alarm and beeps are plenty loud. For comparison, I also have the Casio G-SHOCK 5610u and that has a very hollow and weak alarm. The ProTrek is louder, but not obnoxious by any means. It's probably typical and what anyone would expect. EASE OF USE: If you want a watch to just throw on and intuitively know how to use everything, this one is not for you. It is not hard to use if you are willing to spend a few minutes to get acquainted with it. You will need to look up your latitude and longitude coordinates online (or on a map, I guess) and set them in the watch so that the sunrise and sunset times are accurate. BATTERY and MULTIBAND 6 SYNC: The first day I had it the atomic sync would not initiate, manually or automatically. I soon discovered ATOMIC SYNC WILL NOT WORK WHEN THE BAROMETER WEATHER ALERTS ARE ON. I'm not sure the reasoning behind this, but I assume it is a feature, not a bug. Neither the auto-receive nor the manual-receive work while the barometer weather alerts are on. (Go to the barometer mode, then press and hold the barometer button to toggle it.) WEIGHT: The watch is heavier than my previous 5610, but it's not heavy. It reminds me of my metallic band Pulsar watch. It's a very normal weight for a watch. Overall, it's not a cheap watch, but it's not extremely expensive either. It will satisfy your desire for usefulness and having cool gadgets without getting into smartwatch territory. I have finally stopped endlessly browsing watches on Amazon and youtube. I have found what I was looking for.
