I hardly exaggerate, I work in the industrial field, so lots of welding which proscribes some quartz watches. Here with the Promaster is another world, she takes full day long mouth: welding, grinding, sharp blow, various products ... in short, she is shaken all day long. She is always there (I will like new) valiant. When buying it advanced slightly to stabilize thereafter with a few seconds apart, a trifle. Happiness is the automatic mechanized. A true beating heart (nothing to do with the quartz and beeps from all sides) who lives and who accompanies you. The watch is not very large in diameter (admittedly a bit thick), I would even say discreet, it has a charm. The bracelet pleases me very well because solid. The crown is firm and pleasant to use (I do often use into account time) with a detent 60 clicks and-return, which is more than enough. The lume lasts all night if only one illuminates some time under a lamp, there is enough in the morning to see clearly now. Having the crown at 8:00 is a real plus, not hooking and does not hinder movement. It is rather light and knows how to forget the wrist. Surprisingly its simplicity and charm attracts attention of my colleagues, surprised by the quality of the watch and its automation. A beautiful watch, efficient, accurate and ..... automatic.
