This is my Movado Sub Sea chronograph with the Zeinith 146HP movement, which is a rare enough piece in this condition, but what makes it truly unique is the double tachys as shown. Other, more common examples all have the inner-most tachy on the dial but this is the only known version in existence with the second chapter ring type in the case, making it exceedingly rare and sought after by collectors who without question inhabit the highest levels of the horological accumulation obsession, one of which in particular has been known to begin foaming at the mouth and convulsing when I bring this beauty to the table.
