Swatch Sistem51

Sistem Chic, SUTF400

ETA C10111


This is the second Sistem51 I have bought. I really like my original 'Sistem Chic', though it wears a lot bigger than you'd expect by looking at it. The simple black-and-white design was a little too cluttered, but it appealed to me above the more colourful options. When I saw the new 'Sistem Gentleman', I realised it was a better design for me. I prefer white dials to black, but from my point of view the styling is hard to fault. The hands on this watch appear to be longer, thinner and pointier than on ther models and the markers have been moved to the bezel, making for a less cluttered and larger-looking dial. All good, in my book.

This is a particularly tricky watch to set. The seconds do not 'hack', but may be induced to pause or even run backwards by certain manipulations of the crown. The minute hand is easy enough to align to a marker, but, nine times out of ten, replacing the crown (even with extreme caution) will cause the minute hand to jump one or two (or possibly even more) minutes.

One of the most impressive aspects of this watch is its 90-hour power reserve. I can set the watch running on a Friday; forget about it for the weekend; and come back to find it ticking along on a Monday.

I have read that the Sistem51 is rated to +/- 7 SPD, although I have also heard that it is rated to 10 SPD. I cannot find anything official on this.

Some details for this watch are missing because it is not subject to the same tests as others in the collection.
