This year is a big year for Zenith manufacture celebrating 150 years. Along with other novelties from Baselworld 2015 that we have presented you here, we now bring you another watch released this last week, may we introduce the Zenith El Primero Chronograph Classic. The new Zenith El Primero Chronograph Classic features a pebble shaped case with a diameter of 42 mm and a quite slim profile at 12 mm thick. This new case —featuring a highly polished finish— comes with the nicest pronounced lugs— we've never seen before on any other Zenith El Primero— and with a very clean and timeless design that even includes a domed sapphire crystal. The watch is available in 18K rose gold in a limited edition of 150 pieces and in stainless steel as a regular production watch. The new Zenith El Primero Chronograph Classic is fueled by very strong Zenith DNA in its purest and most classic form.

The sunburst silvered dial in this watch is not only very clean and well-balanced but it also comes with an interesting surprise. What appear to be applied hour markers at first glance, upon further inspection are engraved markers on the dial that are then filled with gold or rhodium respectively.

The elegant hour and minute hands along with the blued hands for the running seconds an the 30-minute chrono register are a perfect contrasting touch to the timeless look of this watch. The elegant thin case features rectangular curved chrono pushers that wrap around the case band as well as a nice and thin Zenith star marked crown.

Both watches equipped with display case backs, allow for full view of the beating heart powering them. We are talking about the El Primero 4069 automatic calibre composed of 254 parts, 31 jewels and which provides a power reserve of 50 hours when fully wound while beating at a frequency of 36,000 vph. As it is the norm with this manufacture from Le Locle, the calibre is beautifully finished and a real treat for the eyes.

Rounding out the elegant and classic look of the new Zenith El Primero Chronograph Classic, both watches feature beautiful alligator straps with metal matching pin buckles. While the 18K rose gold model sports a dark brown strap, the stainless steel model comes with a black one.

On the wrist, the watch wears slightly smaller than its actual size and perhaps a milimeter smaller. Its wrist presence is classic, elegant and simply timeless. One thing to consider is that this watch definitely would look better while wearing long sleeves and dressy clothes, rather than with a casual outfit.

Sticker Price $21,600 USD for 18K rose gold and $8,900 for stainless steel. For more info on Zenith click here.
