Patek Philippe launched the reference 3579 in 1969 and it was only in production for five years. Only made in stainless steel, the reference had two dial variants, matte silvered or blue, like the present example. These watches feature the extra flat 23-300 movement and two piece tonneau shaped cases with screw down case backs – the latter being engraved here.
The presence of the retailer signature on the dial further enhances the desirability. Edward and Benjamin Howes opened a jewelry store in Iowa in the early 1900's, and became well-known as retailers of pearls. The store would eventually close, and Benjamin moved out to the west coast and opened his own jewelry shop, B.D. Howes & Son Jeweler, in 1919, in Los Angeles. Benjamin was able to expand the business on the west coast to include 10 shop locations, and eventually became a retailer for Patek Philippe watches. He died on January 18th, 1939.
