Absolute perfection in a timepiece!!!
The technology in this watch is next level and the look and design is breathtaking! Solar Power and Atomic Synchronisation along with Altimeter, Barometer and Compass! All in a watch that never needs a battery and is always the exact right time! I put a 38mm glass screen protector on this watch to protect it as I’m clumsy with bashing up watches lol. I’d rather wear this watch than a 15k Rolex, absolutely no joke!!!

Reliable and easy to read analogue face
Great watch. Highly legible face. Atomic time keeping and runs of direct and ambient light! What will they think of next?

Near perfect.
The only things that let me down was the negative display which I found hard to read compared with a positive display and no backlight during key presses / functions. Which for a tough solar watch seems bizarre.

Go for G-Shock for £50 more!
Cons- it takes ages to arrive. It is big, it is circular and therefore big all round. It can be boring to many people. The luminescence is not that wonderful, even with the light. No bluetooth (some may say). Pros- it is MUCH easier to set than the horrifying Casio Oak, everything is easier to get to and the crown is hilarious. You can use it as a bedside clock or counter clock when not in use, your own local Big Ben. It is very easy to read with the three-dimensionality of the numbers. Vivre la Thailand!

Strengths: - A generous combination of features. Having triple sensors, multi-region radio time sync, and solar power all in one watch is a boon. It's a high price to pay for it all, but I'm not regretting it. - Straightforward access to functions, with the crown only needed for changing numerical values. - Very readable in the dark without needing to activate the light, thanks to large hands/numbers and amazing glow-in-the-dark materials. - Good radio reception, able to get strong signal from WWVB all the way out in Massachusetts. - Compass almost holds calibration for more than a day, which is great for a digital compass. - Slightly less "tacticool"/overcomplicated appearance than most primarily-functional digital watches, which I like, although it is still quite visually busy. - Alarms work the same and are just as loud as those on any other Casio watch. Some reviewers have said that this watch is too quiet, but mine is loud enough to wake me up in the morning just fine. - Extremely quiet. I have very acute hearing and am easily annoyed, but I can only hear this watch tick when it's right by my ear, so it's never a problem. It's not completely silent like an all-digital-style watch, but it's close enough. Weaknesses: - Somewhat bulky, though well within my limits for size and weight. - The resin band it comes with is a bit uncomfortable, comes undone a lot. Better third-party options are available, though. - The stainless steel bezel is not very resistant to abrasion and has no plastic guards to protect it, making this a substantially more fragile watch than I was hoping. - Weird and garish illuminator. The UV LED it uses to light up the hands and numbers doesn't get them very evenly, and everything glows an actinic blue-violet color that hurts to look at in the dark. The LED that lights up the digital display also leaks a lot of light out at a low angle, perfect for accidentally distracting someone sitting to your left. Overall, using the illuminator is really kind of a painful experience, saved only by the glow-in-the-dark dial that stays visible for hours and often saves you needing to use the light at all. It's certainly better than nothing, and if I absolutely had to do something with the digital display in the dark and didn't have a flashlight, I'd tough it out, but this does really make me miss the blue-green electroluminescent backlights from Casio's lower-end watches. - Terrible countdown timer, bad even for Casio. Not only can you not set it down to the second, but it also doesn't go higher than one hour, which is a downgrade from my old SGW-100 which could do up to 24 hours. I guess it's enough for most cooking, but a lot of cheaper competitors out there these days have countdown timers that can be set up to 24 hours and down to the second, which makes this stick out. I'm honestly not sure why it's so limited, since there's plenty of room on the display for a multi-hour timer and it would be easy for the menus to support setting it. - Unscrewing the crown to change settings is very slow, and so is winding it back in afterwards. You apparently can't leave it out without compromising water resistance either, which is somewhat concerning. I guess it's somewhat nicer than just using buttons to increment a value up and down, but only a little bit, and it's definitely not faster. It's also very easy to overshoot your target thanks to somewhat strange fast-scroll behavior. - Using the digital display at certain times of day can be difficult because the hands get in the way. I know this is just a fact of life for analog/digital hybrid watches like this, but it's not mitigated very well here. The display is very tiny, and the hands, especially the minute hand, can cover a lot of it at once. There's a trick where you can press the light button and the bottom left button simultaneously to make the hands temporarily move out of the way, but it resets whenever you press any button, meaning that you can't keep the hands parked while you use the stopwatch or something. It's always technically possible to see every part of the screen by peeking at it from multiple angles, but between about 24 and 36 minutes after each hour of the day, it's kind of awkward. I'm happy with the watch overall, and can see myself wearing it for years to come - but it might also be the first watch that I actually bother to take off before doing anything that might risk scuffing it, and I'm not sure how I feel about that. Next time, I might go for something a little cheaper and better-protected against abrasion, even if it means sacrificing a few of the nice features this one has.

En general es un reloj que cumple con creces su función y su diseño, es mi primer Protrek y no podría estar más satisfecho, se que será un reloj que me durará décadas y estoy muy feliz con él. A continuación les dejo mis impresiones : PROS: *Los números son grandes y facilita mucho la lectura al menos respecto a los que solo tienen el 3,6,9 y 12 o los que de plano tienen puras líneas *Es Tough solar, por lo que no tendrás que preocuparte por la bateria *Tiene barómetro, brújula, termómetro, altímetro, cronómetro, temporizador, alarmas, sincronización por radiofrecuencia. En general, este reloj es una caja de monerías que le servirá más que nada a los que gustan de actividades al aire libre como ciclismo o senderismo. *Tiene una pantalla de display negativo grande y elegante con retro iluminación, así como un LED que ilumina las manecillas y los números. *Los números, las manecillas y el contorno del reloj tienen un material fluorescente que facilita la lectura en entornos de total oscuridad. *Es resistente al agua, hasta 10 BAR de presión. *Las correas son de fácil instalación, por lo que puedes comprar nuevas de la misma medida y personalizar tu reloj (La medida es de 24mm) CONTRAS *El diseño es muy deportivo, así que no es un reloj que puedas usar en ocasiones muy formales (aunque obviamente no fue hecho para ello). *La pantalla puede ser difícil de leer al ser un display negativo, en especial en entornos de poca luz, al atardecer o en habitaciones medianamente oscuras. *La interfaz del menú es relativamente compleja, sumado a esto, el manual no hace un buen papel al explicar el funcionamiento de la lógica de la interfaz, es mejor buscar algún video en Youtube sobre como configurarlo. *el sujetador de la correa se mueve con el uso normal, por lo que constantemente debo ajustar el sujetador para que no sobresalga el excedente de correa perforado.

Keeps working after salty ocean! I washed them in a drinking water after, each time. I can read time from any angle at huge distance! Always fully charged. Compas and air pressure stat!! Light is more than enough to see at night. Luminescent keeps it for a few hours at least! Radio bands - no need to do any maintenance - ALWAYS CHARGED from the Sun and ALWAYS CORRECT TIME from radio bands. One minor drawback - I find the settings crown less convenient than just buttons.

Big face dial, very visible numerals, plenty of features for a very beautiful watch. Can wear it all day indoor & outdoor, very comfortable.
