This is the second watch of this brand that I've bought for myself. I lost the first one when I carelessly put it in my bag at the sports field (or maybe it was stolen - that's an open question). At first, I bought other watches, but they lacked convenience, although they were stylish. In the end, I returned to this design; this option is the closest to what I want: elegance, convenience, style, nothing missing.

Always wanted a watch in this style. the berny version seems very well made and looks spectacular.

A nice little watch that looks good and keeps time reasonably well. the standout features are the design and the lume.

This is lovely. i had a seiko craftsmanship that broke within 6 months. this watch is as good in most ways but was a tenth the price. i even really like the strap. the movement is smooth and power reserve very good. lume is incredible, and visibility superb night and day. i highly advise you to buy !
