The Documentary Anchor
In April 1956, 64 Mishbatzot carried an advertisement for “Chess Clocks Made in Israel” by H. & J. Benjamin, Clocks & Watches Manufacture & Export, 167 Jaffa Road, Jerusalem.471
The Historical Meaning
The notice places domestic Israeli chess-clock manufacture in the first decade after independence, not merely later import or club use.
The Object Type
The advertised form is a standard two-dial mechanical chess clock with top-mounted plungers and a conventional player-to-player switching system.
H. & J. Benjamin, Jerusalem — advertised 1956.
Historical Significance
The Benjamin advertisement is unusually valuable because it identifies the maker, the Jerusalem address, the product category, and the claim that the clocks were made in Israel. It provides a firm documentary anchor for Israeli chess-clock production.
