The Zenith El Primero LIghtweight 10.2260.4052W/98.R573 is a limited edition of 100 pieces of the brand's iconic El Primero chronograph model that has been put on a strict diet. Its caliber 400B Titanium movement features many titanium parts, making it 25% lighter than a classic El Primero at 15,9 grams. The case is done in ceramicised aluminium and carbon, with titanium pushers and crown. The openworked dial features three different-coloured counters.
