Rare Heuer Quartz Ref 365.215 38mm. I assume this watch was made for Saudi team who ended up boycotting the games in Moscow along with 61 other nations due to the Soviet invasion of Afghanistan and of course Oil. Saudi was the first team to pull out. The watch was made for Saudi football team, dial reads "Alnasser Saudi Club Riyadh, established 1955"This is the only know example of such a watch so it may well have been a prototype. £1500
