Room I · The Maker
Longines, founded at Saint-Imier in 1832, built its name on high-grade, thin calibres and on meticulous record-keeping, the firm can still trace a movement by its serial to the day it left the factory. The Cal. 17.95 in this watch was one of those refined thin movements, invoiced in 1924 and cased more than a decade later for the occasion this piece was made to mark.

The Object
An 18k gold Longines pocket watch given as a family gift in Amsterdam in 1937, complete with its original box, certificate, and the note it was given with. Documented from the day it was given.
On the 8th of October 1937, in Amsterdam, Cisca Tombrock turned seventy-five, and she marked the day in a way few grandmothers could: she gave each of her thirty-three grandchildren an identical gold Longines pocket watch. This is the one that went to seven-year-old Wim Vroom, and the case back still carries the gift in Dutch: Aan Wim Vroom ter gelegenheid van Oma's 75sten verjaardag, Amsterdam 8 Oct. 1937.
The family could afford the gesture. Cisca's husband Willem Vroom had co-founded Vroom & Dreesmann in 1887 with his brother-in-law Anton Dreesmann, building it from a single Amsterdam shop, fixed low prices, cash only, into one of the largest department store chains in the Netherlands. Wim himself took another path: economics, then art history, then the Rijksmuseum, where he directed the Department of Dutch History from 1971 to 1995.
It later left the family and passed through an auction house unrecognised. A specialist Dutch dealer bought it, noticed the engraved name, traced it back to the Vroom family, and the family confirmed the story. Everything given with it in 1937 is still with it now: the fitted presentation box, the signed Longines Certificat de Garantie dated 20 October 1937, the woven chatelaine cord with its fob seal, the leather pouch, and the original handwritten gift note.
The watch itself deserves the story. It is an open-face dress watch in solid 18k gold, 44.4mm, in a curved step case, with a clean, unrestored cream dial, applied gold lance markers doubled at twelve, matching gold lance hands, a dot minute track and sub-seconds at six. The movement is one of Longines' high-grade thin calibres, invoiced by the factory in 1924 and cased thirteen years later for the birthday; its serial matches the case and the certificate exactly. It winds, sets and runs well.
The marks, the movement and the condition are set out piece by piece in the drawers below; the gift and its papers are set out in Provenance.
