The Zenith of Lightweight Chronographs



There is a term for cyclist that applies to those of us who ride that are obsessed with getting a bike as light as it can get.  They are called weight weenies.  Well, for you weight weenies out there, meet your watch.  Zenith is releasing a limited run of their El Primero Chronograph that tips the scales at a mere 15.9 grams.  That is a bit over 1/2 an ounce, or to put it in another context, about 3 seedless grapes.

That in and of itself is pretty impressive, but realize that this watch has an automatic movement and a 50 hour power reserve.  How do they get the weight so low?  Titanium and carbon fiber, with a bit of aluminum as well.  The case itself it aluminum and carbon with titanium pushers and a crown.  There is a sapphire crystal up front and another for the exhibition caseback (waterproof to 100 meters), and the face is highly skeletonized around the eyes for the chronograph functions.  So there is a lot going on with the dial, but it is still pretty legible, all packed into a 45mm think and 13.2 mm tall package

The movement is the El Primero 400B, redone in titanium to shave 25% of the weight, with 31 jewels and beating at 5 Hz.  The oscillating weight is finished with a “Côtes de Genève” pattern and decorated with the Spindrift logo, to commemorate the partnership between Zenith and Spindrift Racing (a multi-hull sailboat racing team).  The watch comes on a Nomex-coated black rubber strap with a PVD triple folding clasp.  It is being offered in a limited, numbered edition of 250 pieces.  zenith-watches.com

Thank you for reading this WristWatchReview post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.

WristWatchReview is one of the few remaining truly independent watch news outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent watch sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis. We don't play the games the other sites play and we've paid for it when it comes to ad revenue.

We would love for you to support us on Patreon and every little bit helps. Thank you.
