Tudor. It's all in the way we make a Tudor. Nearly impregnable. Machined from a solid block of incredibly tough stainless steel. With the famous, pressure-proof, Oyster case adn screw-down crown. Armored to take on dust, water, shock, magnetism, knocks, bumps, trails, tribulations and the day to day indiginities that face any watch. Tudor. Smart, sharp and designed to endure the test of time. Eduring at time itself.
