With Patek Philippe Extract from the Archives confirming production of the present watch with 8-day lever movement and silvered nickel case in 1868 and its subsequent sale on 29 June 1875.
This watch is one of the exceedingly rare timepieces made by Patek Philippe fitted with a long duration 8-day movement and an oversized case of robust construction as required for navigational use on board ships. According to Patek Philippe Museum - Patek Philippe Watches - Volume I, p. 66, the entry for watch no. 35'150 from the same series, it would appear that Patek Philippe made only twenty-four watches with an eight-day movement of this type, numbered 35'139 to 35'162. Twenty-one of them had cases with engraved coat of arms; all were purchased by a client from Budapest, rendering the present watch one of the only three examples, including no. 35'150 in the Patek Philippe Museum, without engraved cases.
Fresh to the market, this 8-day watch is furthermore preserved in very good, original overall condition.
