JOS was started in 1920 as something its name promised: a club for kids, run by people who believed organized sport could keep working-class Amsterdam children out of trouble. It was one of the smaller fish in a crowded Amsterdam pond - never famous, never rich, but durable. By the time Michels arrived in 1960 the chairman was Jaap Knol, himself a former Ajax player and Dutch Olympian, who had presumably seen something in the young coach worth gambling on. Michels stayed four years. He went on to AFC for a season, then to Ajax. The rest is in every football encyclopedia. The plaque acknowledging where it actually started is in a clubhouse a tram ride east of the Olympic Stadium, and most fans have never set foot there.

In 1987 the Dutch art-pop band The Nits put a song called 'JOS Days' on their album *In the Dutch Mountains*. Henk Hofstede, the band's singer, had grown up nearby. The song remembers a war monument that once stood on the club's grounds - a small memorial to JOS members killed in the Second World War - and it remembers the sting of being the first-born and somehow not quite welcome. The original monument was demolished in the years that followed; comparable monuments to fallen footballers still stand at other Dutch clubs, but not this one. A pop song outlived the stone. Hofstede's lyric is the rare case of a Dutch amateur club preserved in three minutes of music.

By the 1990s JOS, like a lot of small Amsterdam clubs, was running out of members. In 1995 it merged with a neighbor called Watergraafsmeer to form what is now JOS Watergraafsmeer. The Watergraafsmeer side of that merger had its own complicated lineage - it had itself been built from six earlier clubs, all with the kinds of earnest acronymic names amateur Dutch football specialized in: TIW (*Trainen Is Winnen* - Training Is Winning), Amstel, RNC, TDO (*Training Doet Overwinnen* - Training Wins), WMHO (*Wie Moed Houdt Overwint* - Who Keeps Courage Wins), and Ontwaakt (Awaken). The new club kept JOS's name first. Whether by sentiment or branding savvy, the older identity carried.

On 24 September 2014, JOS Watergraafsmeer got the gift and the punishment that every amateur club secretly wants: the KNVB Cup paired them with AFC Ajax. The two teams met at the Olympic Stadium - the first official Amsterdam derby contested in the city since 1983. Ajax won 9-0. Their Polish striker Arkadiusz Milik scored six of those goals himself. On JOS's side that night was Davey van 't Schip, son of former Ajax player and assistant manager John van 't Schip - a small, neat circle of Amsterdam football closing on itself. The result was brutal. The story was sweet. For one evening, a club Rinus Michels once managed shared a pitch with the institution he eventually transformed, and the cameras were rolling.

JOS Watergraafsmeer today is what it has mostly always been: a community club whose Saturday team plays in the *Derde Klasse* and whose Sunday team competes in the *Vierde Divisie*, four tiers below the professional ranks. In 2023-24 the Sunday side finished third in Vierde Divisie A and made a serious run at promotion to the Derde Divisie. They beat VV Staphorst 5-4 on aggregate, lost to RKSV HBC in the final, then got a second chance through a 'losing finalists' playoff after OSS '20 withdrew. They lost the semifinal 3-2 to GVV Unitas. A near miss, in the Dutch amateur way: heartbreaking on the night, ordinary by Monday. The club is now in its second century, still on the same patch of Watergraafsmeer green, still feeding the occasional player toward bigger leagues.
