    It will be a good training for soldering surface mount parts. Because there are few parts, if you are used to it, it will be easy to complete in about an hour. It seems that it has a built-in calendar until 2099, and when you set the date it displays the exact day of the week. In the time setting, you can set up to seconds. The kit sent to me had a translucent acrylic shell. Can you choose transparent or semi-transparent one?

    This was my first attempt with SMC soldering, and I managed this quite eaily. Major issue was to read the resistors' references, but with a magnifier or a close up picture, it was OK. I also had to track one dry join (one colomn of the display remained off), but looking at were this led block was coming from, I fixed it. Only minor problem remaining is the buzzer, but I don't need the alarm clock feature. A bit too bright even at lowest level, and 3°C accuracy for temp, which is a bit high. Anyway, a fun product !!

    After installed all the components except the display, there is no alarm sound when testing. But I can hear some beep like I touching the touch button. I go ahead to installed the display, and I can see the clock is working but sometime the Time menu displayed. I know there is some problem with the switch. 4 hours try to figure out what is the issue, finally all working fine except the sound barely can hear it. Just re-solder everything solved the issue. Even really tough to solder the SMD components, I love the clock very much.

    Hello, I am from Amsterdam Netherlands. I have buy this clock and put it together. I must say I am not a expert on this. The soldering with a big solder was to complicated and I have used a mini solder for better result. After assemble the clock the display was not working good. A few matrix blocks are not working. The problem was the main big chip. I used to many solder on that chip. I removed so 70% of the solder with a copper Itze wick. A sort of streng of Cooper to absorb the solder from the chip. After that everything is working in fine order. Only the temperature chip is not working correctly,but all the people here has a problem with that,you can not help that. Now I have a nice transparant clock. For all the people with problems of the clock,check the main chip, don't use to much solder. A better way is to use solder flux to spread the solder better on the chip and do not use a big solder but a mini solder station. This is not my last clock,a have order two more to praxis on it. And than I can give it away for a present to family ore birthday present.

    The package came in a normal envelope with some protection. Bring some extra small pieces in case there is a problem. I am a beginner welder, and the assembly has been complicated by the size of the parts and the proximity of the welds. I've had to redo some. The result is a nice watch with customization options.

    watch is good but if you have any experiance about soldering you will be disappointed.parts are very small mounting is hard.

    Not for the faint hearted to assemble :) Yet, not very very hard. Just have some experience and patience and it's a fun job!! Does not beep, just a small "burp". Measured with an oscilloscope and I see the +5v square pulse in the buzzer. Seems probably a passive buzzer is being sent instead of an active one. But, otherwise, it's awesome and accurate.
