Great value

Ideal watch for running . Was looking for something with basic features eg: stopwatch/time . It's overall good quality watch for the price.


The lap recall is not as good as I expected

Great value watch!

Love the colour (blue/grey). Numbers easy to read. Large face-size if you have a small wrist. Band fiddly to adjust as there's a nodule to lock it in place. Would be better with a light to check time at night. But great price.

Deal Breaker

There are so many great things about the design, the color, and the intent of this product, BUT after purchasing it and finding that there was this ONE basic thing that was not deemed as absolutely necessary by designers was actually the very thing that was needed to make this a 4-5 star item. This product is so beautiful and simple and in the right price point which was exactly what I was looking for. I have to also praise the wonderful design feature of the straps being given the added switch button that would presumably allow you to remove the straps with ease for changing them if needed--which shows that this product was designed for the intention to be used and kept for a long time. The color is also very mature and sophisticated, not overly patterned with loud colors or prints like a little girl's, and the overall sleek and simple buttons were great. HOWEVER, not having a backlight became a deal breaker for me, as this means no running with this at night. Also, because this product also included a watch feature (telling time), no backlight means not being able to see the time in the early morning (before dawn) if you slept with the watch and were using it to tell time and go for a run after waking up. Not having a backlight reduces this product to just being a fancy wrist-stopwatch which you have to essentially keep removing and rewearing only when running in broad daylight. But since this item is so perfectly conducive to be so easily integrated into your life to and from running, sleeping with it, swimming with it, washing hands with it, if only the backlight was a prerequisite basic feature, then it would have hit a home run. It seems very disappointing that even the waterproof feature is wasted on this since not having a backlight also doesn't make it useful in the pool in shadowed areas. The price point is really great and the greater value would have been there if there had been a backlight as one of the minimum features. I paid HKD59, but the next price point for the next available running stopwatch model in the store currently (HKD199) does not justify the purchase of a 230% price jump just for getting the minimum backlight. A recommended added feature that would have also been nice to have would have been an option to have the telling time in the watch feature part shown in a digital dial rather than only in 24H or 12H numerals. The visual dial even if in digital form is still a classic yet functional way for dividing and visually counting our time in additional to the already existing stopwatch features. Not having that backlight renders this item a much less useful product and therefore renders it somewhat too ancillary to just buying a normal branded sportswatch that has these features (including a stopwatch) all in one already.

Bought for the strap

I bought this because the full watch was significantly cheaper than trying to buy a replacement strap for my Garmin 645, either from Garmin or even at the street market in Sham Shui Po! (I guess I was being offered only the foreigner's price...) The strap is wonderful :-)
