Proposed in a Special Limited Edition of 500 pieces, Chrono 4 Géant Titane celebrates 10 years of chrono 4. A commemorative series with “black or” dial, on which the large red roman numeral “x” stands out, as a symbol of a decade of passion, research and technique, in the purest swiss tradition. Also the caseback, personalized with the ebgravings “2001 – 2011. 10 ans de chrono 4”, celebrates this anniversary.
