Pleasant are the very low weight, low profile included planem sapphire crystal, a simple analog display held discreetly inserted digital display, the size of the readability somewhat difficult in the elderly.
Compared to the older model, the new also an analog second hand (!). I personally very important, as well as the timer which can be set to 99 minutes. Lovely, too, that the display of the days no longer must be in English, but also German abbreviation can be set. The beep when switching the digital display in other modes is also switched off. Then the clock does not beep, however, when you turn the timer or stopwatch.
What's not so good: For the entire operation Casio sees only 3 buttons in front. That's true, but brings restrictions: if one of the 5 alarm times set, or should only be activated as when adjusting the timer, you have to press the same button, which also switches on the lighting. So no readjustment without lighting, although the course, the battery is charged. The settings for the alarm time or the timer can be done only with a button counts upwards. Correct down will not do. For the change while pressing down the button goes relatively quickly. But who let go too late, "pleased" about an extra round. The har Casio in the past much better resolved. My final clock 100D-professional criminals had 5 buttons including recessed "Adjust" button, which was used solely for the start of settings. The button on the left is the way small and round, what feels uncomfortable. The buttons on the right are larger u. To operate more comfortable.
For solar function: How good is, will only become clear in a few years. I do not feel euphoria here. 6 years ago I had (see above) with radio and solar function bought my previous Casio u also thought:.. "Never change batteries". After 3 years, I had to replace the battery, although the display indicating always full charge. When using the lighting, the clock since switched but in a recovery mode, which temporarily reduces functionality. Light no longer existed. Another three years later appeared the same problem with the new battery back up.
In the instructions for LCW M150T is the way that the rechargeable battery has a limited shelf life. If such a battery needs to be replaced but after 3 years, where then is the advantage of the solar function? Casio also offers watches that are run with a battery 10 years. 6 years ago I'm so risen as a temporary replacement. Now, 6 years later, she still runs in any case, but without wireless functionality.
Despite extensive criticism but I am for the time being quite pleased with the "new". And as for the solar function now provides, will prove in the coming years.
