If you look at Idealo by Titan-Flex belts can be seen that not come cheap, so it's ok if it's not super thin for the price. The clock itself makes a good impression so far also. Accuracy seems good so far, dial and hands not quite in sync, therefore, is often second hand between the bars on the dial and not always close attention. Durability can I not anything to write. Silently they way, is not as noted elsewhere herein, but quietly.
Addendum to review, a few days later I got by chance the clock at Amazon "Warehouse Deals" seen as returns, good for amazing 15 state. For one out of curiosity to others because of the Flex band I've just ordered again. Delivered was a clock in like new condition, even the protectors were front and rear plan yet. The adjuster was pulled out and therefore the clock did not work, maybe the thought in the Retoureabteilung is broken? But works just fine. Very nice, battery and a flexible strip on reserve. This clock I've also put up the same times. Standard Movement from Japan, very tiny "Japan" engraved. Determined millions installed in various cheap watches, in women's and men's watches. Movement is substantially smaller than the housing to the movement is a plastic ring which also maintains the battery. Battery of Seizaiken, battery type SR621SW. Movement is nothing special, but does not have to be bad. Had 20 watches which perfectly over many years ran with similar or even the same movement. The were still exactly as the housing already completely scratched and was over and after a few years in the drawer still. But you should be aware that this is a movement that is installed is to look for 20 watches. If you have the Flex tape still on it which can be expected to pay for everything already properly. You get nothing for free normal maintenance, or too cheap, at least not regularly.
