horological masterpiece preserved for over three decades by a discerning Hong Kong-based collector.
Produced circa April 1988, this represents a very early example of the coveted second series (1986-1991). Bearing
the movement number 875130 and case number 2831374, this 3970E is definitively authenticated as one of the
earliest iterations of this iconic reference’s second series.

The watch presents in remarkable condition, a testament to its meticulous preservation. The crisp case maintains
its sharp, well-defined angles Most captivating is the original dial, which has gracefully evolved into a beautiful
vintage cream tone, adding warmth and character that only decades of careful ownership can bestow.

This particular example offers the collector’s advantage of dual casebacks - both the elegant sapphire crystal
display back revealing the intricate movement within, and the original solid caseback. The hallmarks stamped
on both the inner and outer surfaces of the caseback remain exceptionally crisp and deep.
