Circuito Permanente del Jarama

When Formula 1 arrived in Jarama in July 1967 it was the first time Spain had hosted a Championship Grand Prix since Mike Hawthorn beat Fangio's Mercedes back in 1954. A purpose built circuit designed by John Hugenholtz (also responsible for Zandvoort and Suzuka) was built on a small pocket of land in the arid scrub land north of Madrid.

The 2.11 miles circuit consisted almost entirely of tight twisting corners and so could be considered to have been ahead of its time! Jarama staged a total of nine Grands Prix before the track was declared too narrow cars although it was never popular among the drivers.

The first F1 race was a non-championship affair won by Jim Clark for Lotus. Graham Hill, also with Lotus won in 1968. After a trip to Montjuich Park in 1969, the Spanish Grand Prix returned to Jarama for 1970 where despite starting from pole Jack Brabham could not contain the onslaught of Jackie Stewart who stormed to victory. Despite the Scot's valiant drive the race stands in memory as a result of a collision between Jackie Oliver's BRM and Ickx's Ferrari. A huge fireball ensued. Combine that with water all over the track and there was little surprise when several cars spun out.

In 1972 Emerson Fittipaldi marked himself as a title contender with a win ahead of Ickx, while the 1974 race was a one-two for Ferrari as Lauda headed Regazzoni home. The 1976 race was plagued with controversy. James Hunt was initially disqualified and the victory passed to Lauda, albeit temporarily. 1977 & 1978 both fell to Andretti and his Lotus, who also finished third in 1979 just behind Depailler and new team mate Reutemann.

In 1980 at the heart of the FOCA/FISA dispute the race went ahead without the 'grandee' teams of Ferrari and Renault. As a result championship status was withdrawn after Jones had won for Williams. The fact that overtaking was so difficult here meant that the circuit rarely produced great races, although it was that very factor that made the 1981 race so interesting. Gilles Villeneuve scored a memorable win in his dog of a Ferrari, despite having Laffite, Watson, Reutemann and de Angelis all within a second of him at the finish.

That was the last Grand Prix to be staged at Jarama for it was five years before Spain was returned to the schedule, following the opening of Jerez.

Since it's departure from F1, Jarama has continued to host motorcycle races alongside the odd outing by sports cars.

So that's some information about the racing circuit; I will leave it to others to provide information about the chronographs. We do have a photo of a black one OnTheDash; they are more common in a gold color.
