Aquacy Hei Matau TradeWinds Chronograph 200M White Panda Dial Men's Watch, sapphire glass: I already have a well working diving watch 300m from Aquacy (mechanical calibre) and it works very well! But I needed an every day watch using it in my workshop with power tools. There we are having a fine watch by the housing and bracelet, all top quality and keeping the time well with the standard quartz calibre OS10 from Miyota with no jewels inside. Sorry, I think that a well made quartz calibre does not need any jewels, if you are happy with 20+/- seconds a months at all. The contemporary oils in the calibre are made to last for about 10 years before one thinks to service the module. Anyway the calibre is rather modest in price to buy on the market, cheaper than a servicing the old module entirely and replace it. Therefore I bought three new calibres for less than 80 Pound Sterling and keep them in a dry box each packed individually when I need them in future. I would call this watch by appearance and workmanship on the housing and bracelet a real thing in sustainable terms and you might follow my advice to buy another calibre therefore as a backup for late future. Very happy with service and product. J.Hotz

I consider the panda watch it´s a classic and this undoubtedly leaves me satisfied since it is very light, it has a chronograph function, the 120 click of the bezel is nice, as well as the 42mm are the perfect size for me. Excellent customer service!!!
