Sinn Chronograph Tachymeter Limited Edition Watch

German Sinn timepieces are really hard for us tool watch lovers to resist. Often stalwart in their new products, over the last few years they have been a bit more trendy and playful. While I don't know first hand, I have a feeling that the Bell & Ross success was a major eye-opener for them. Back in the 1990s when Bell & Ross began, they were basically selling dual-branded Sinn watches in a new distribution method. It was basically like selling the best tools in a hardware store, but now in an department store. Bell & Ross has since come a long way, but their roots in offering plain and simple instrument watches hasn't changed much.

I've noticed Sinn starting to offer more limited edition models, especially those that play into the vintage watch theme. Here is one such limited edition model that will surely appeal to Sinn and vintage watch lovers. This is the Chronograph Tachymeter - and is sort of exclusive for the German market (though anyone can get one). The Chronograph Tachymeter revisits the old style "snailed" tachymeter spiral scale and vintage colored lume. All matched to a light brown strap with racing portholes. It is a sort of neat piece that combines a vintage appeal with the traditional Sinn ethos.



Sinn uses an all high-polished steel case that is 41mm wide. It looks great matched with the black rotating diver's style bezel. The chronograph pusher are simple plunger style to add to the vintage feel. Over the dial is a domed acrylic crystal - typical of older sport watches. The case is water resistant to 200 meters. Sinn likes to point out that the dial is done in a matte black tone. You'll notice a picture of white with the "aged" yellow look of the hour markers and lume on the hands. Sinn designers did a good job of creating that iconic spiral scale on the dial, but also not making the dial look too busy. Part of this has to do with the diminutive gray colored subsidiary seconds dial, and well-integrated date window. I really don't think anyone is going to use the tachymeter function, but it looks cool enough.

Inside the watch is a modified (some registers removed) Swiss ETA Valjoux 7750 automatic movement. The attached leather strap is something I wouldn't have guessed to see on a Sinn timepiece. Nothing wrong with it, but it isn't the type of style I usually associate with the brand. This is a special product meant to fit into a certain vintage themed. While uncharacteristic for Sinn to do this, it came out quite nicely. Sinn will produce just 100 pieces of the limited edition Chronograph Tachymeter watch. They have done so for a German online and catalog retailer called Manufactum.de (see the Sinn Chronograph Tachymeter watch via them here). Price is 1,350 Euros.
