The Ref. 16523 belongs to the highly regarded Zenith-era Daytona generation, produced from 1988 until 2000. These references marked a significant milestone in the collection's history, introducing automatic chronograph movements to the Daytona for the first time. Powered by a movement derived from the legendary Zenith El Primero, the Ref. 16523 has become increasingly sought after by collectors, particularly in well-preserved, original configurations. This two-tone example represents an important transitional period between the earlier manual-winding Daytonas and the modern in-house calibre generation.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch5\u003e\u003cstrong\u003e\u003cspan\u003eCase \u0026amp; Details\u003c\/span\u003e\u003c\/strong\u003e\u003c\/h5\u003e\n\u003cp\u003e\u003cspan\u003eThis Cosmograph Daytona features a 40mm stainless steel and 18ct yellow gold case with a black chronograph dial, applied hour markers and contrasting gold detailing.
