Casio Protrek PRW-S6100Y-1JF RM Series Multi-Band 6
Low-temperature resistant (-10 deg. C) Even temperatures as low as -10 deg. C have no effect on this watch. Solar Power A solar cell provides power for operation. Radio signal reception (EU, USA, Japan, China) Whether in Europe, North America and Japan or in the outer reaches of Canada, Central America and China - once the watch has been set to the local time, it receives the relevant signal and shows the correct time wherever you are. In many countries, it also sets itself automatically to summer and winter time. Neo-display A luminous coating provides long-term illumination in the dark after only a short exposure to light. Barometer (260 / 1.100 hPa) A special sensor measures the air pressure (measuring range: 260/1100 hPa) and presents this on the display in the form of a symbol. This enables early detection of weather trends. Thermometer (-10 deg. C / +60 deg. C) A sensor measures the ambient temperature around the watch and displays it in deg. C (-10 deg. C /+60 deg. C). Digital-compass A built-in direction sensor detecs the magnetic north. 10,000 m Altimeter A pressure sensor detects changes in the air pressure and converts the result into an altitude up to 10,000 m. Height Gain The height gain sums all the meters you have climbed in a session, so that you can see at a glance the total ascent on a tour. Altimeter data memory Depending on the model, up to 40 sets of elevation data can be stored in the watch s data memory and re-accessed at any time. Each of these data sets consists of a measured altitude as well as the date and time. In addition to the individual altitudes, the maximum and minimum altitudes during a measurement are also stored. World time function Displays the current time in major cities and specific areas around the world. Stopwatch function - 1/100 sec. - 24 hours Elapsed time, split time and final time are measured with 1/100-sec accuracy. The watch can measure times of up to 24 hours. Timer - 1/1 sec. - 1 hour For fans of precision: the countdown timers help you to remember specific or recurring events by giving off an audible signal at a preset time. The time can be set to the nearest second and up to 1 hour in advance - Ideal for people who need to take medicines every day or those who do interval training. 5 daily alarms The daily alarm reminds you about recurring events with an acoustic signal at the time you have set. This model has 5 independent alarms for flexible reminders of important appointments. Automatic hand adjustment The automatic hand adjustment function checks the home position of the hands every hour and corrects it if necessary - either by adjusting e.g. from shocks or using the influence of magnetism. Button tones on/off The button tones for using the mode button can be turned off. This means that the watch no longer beeps when switching from one function to another. Preset alarm or countdown timers remain active when the button tones are deactivated. Hand Moving Function With a push of a button, hands are moving and permit a free visibility of functions like stopwatch or date. Crown button lock Secures the crown button from accidental change to another mode of operation. Smart Access Technology Smart Access makes it easy to operate multi-function watches. Simply pulling out and rotating the crown provides intuitive control over all functions Automatic calendar Once set, the automatic calendar always displays the correct date. 12/24-hour timekeeping Times can be displayed in either a 12-hour or 24-hour format. Mineral glass The tough mineral glass resists scratching. Resin case Resin Band/Solid Band Adopt a breath type of band of composite design of urethane and a fine resin material with a metal insert. Battery level indicator An indicator shows the current battery level. Water resistance classification (10 bar) Perfect for swimming and snorkelling: the watch is water resistant to 10 bar / 100 metres. The metres value does not relate to a diving depth but to the air pressure used in the course of the water resistance test.

Pros - positive display, light, comfortable, LCD window has light.Altimeter to 1M increments. Barometer alarms. Cons - Would prefer world time to only be displayed in the LCD window like the prw-550. Doesn't need second function dial, just clutters. No sunrise/sunset/tide info.

Can't say anything negative about this watch. I'm a watch nut and I've owned many. This is by far one of the best. Love all the functions, it is lightweight, looks good for casual as well as for more upscale dress needs.

I own the red rescue Mudmaster and that watch is huge/bulky. Very nice, but was looking for something slimmer that still had the ABC functions in a analog/ digital watch. The PRW-S6100 is much slimmer than the Mudmaster and I do not have to contend with that negative display. Very easy to configure the 6100. Same as the Mudmaster. I love the dark green inner bezel with the black outer aluminum to contrast. Pricey? Yeah, but I saved up for it. That breaks my budget for another Casio this year! Here in the USA you don't find these models at all. So far, all of my purchases from Japan have been great. Took about 11 days to get here on the East Coast, but that it good considering. The analog and digital work well together. The light is bright enough to allow you to see ... MoreI own the red rescue Mudmaster and that watch is huge/bulky.
