Our April online sale offers rare and unusual finds both in the horological and early optical apparatus fields. Highlights include a rare single-owner Rolex 6239 “Paul Newman” Daytona, four 18kt gold English watches from the historic wrecked steamship Pulaski, a collection of astronomical regulators from the Norfolk Southern Railway, a fine example of an early Willard patent timepiece with its original stencil decoration, and the monumental “Clement Clock,” with a story not to be missed. Also on offer are a rare complete example of Carlo Ponti’s Mégaléthescope with the original carved wood and marble table and over forty original slides and the final installment of Pennsylvania surveying instruments from the Robert C. Miller Collection.
