Interesting Facts
The 'Fifty-Eight' moniker directly references the year 1958, when Tudor released the legendary Ref. 7924 'Big Crown', which was water-resistant to 200 meters. The modern BB58 was a massive industry hit upon release for finally giving collectors the smaller, slimmer proportions they had been begging for.
