If you like skeletonized watches but you can't afford to go with an independent brand like Armin Strom or with an openworked Royal Oak from Audemars Piguet, lately Zenith has been doing a great job at adding skeletonization to their watches. Therefore, the new Zenith El Primero Chronomaster Grande Date Full Open ref. 51.2530.4047/78.C810 could be the perfect option as far as a skeletonized watch without having to break the bank.
