IWC Ingenieur Titanium Reference Guide

Key Points from the Discussion

• Grand Seiko's 'Brilliant Hard Titanium' is highlighted as a benchmark, being as light as pure titanium but twice as hard as stainless steel, offering superior scratch resistance while still allowing for Zaratsu polishing.
• While IWC claims titanium machining is a 'true feat of engineering,' it's noted that IWC, through its Porsche Design collaboration, has been producing titanium watches since approximately 1980, suggesting extensive historical expertise in the material.
• Grade 5 titanium (Ti 6Al-4V) is identified as the 'workhorse' alloy, accounting for 50% of global titanium usage due to its high strength-to-weight ratio, useful formability, and corrosion resistance, making it ideal for aerospace, medical, and marine applications.
• Seiko's long-standing proficiency in polishing titanium is demonstrated with examples of watches from decades past that still retain their polished finishes after significant wear, challenging the notion that titanium is inherently difficult to finish.
• The increasing emphasis on specific titanium grades like 'Brilliant Hard' or 'Grade 5' by watch companies is seen as a potential driver of 'grade inflation,' leading to higher prices for titanium watches.
• The sandblast finish and subdued color scheme of the titanium IWC Ingenieur are appreciated for imparting a true-to-its-origins tool-watch aesthetic.
