When Swatch announced the Sistem51 at Baselworld 2013, watch enthusiasts took note. The mechanical, machine-made wristwatch was lauded for its simple movement architecture (51 components anchored to a central screw) all hermetically sealed against potentially damaging environmental elements. While the introductory models featured a linear, constellation-esque pattern on the dial, these new versions (excepting the pink watch) are more conservative in design. Luckily, the Sistem51 will still be offered at a reasonable price of $150.

We won't get too deep into technical details in this post; for that, we recommend reading our hands-on review of the Sistem51 here. In summary, notwithstanding its plastic construction, the Sistem51 marks a step forward for Swatch in terms of product concepts and production techniques.
