⌚ Professional Dive Watch Cases & Components

Large-diameter case body (>40mm) with crown guards, threaded crown tube, drilled lug holes, caseback threading, and bezel interface

Design Principles

Material: Grade 5 (Ti-6Al-4V) is known as "Grade 5 titanium" in watchmaking, offering superior scratch resistance vs pure Ti, deep anodizing colors, and full hypoballergenic properties.

Form: Bar stock is CNC machined to form the case body. The high strength of Grade 5 allows thinner case walls at equivalent pressure rating compared to CP-Ti or steel.

Engineering Trends

  • Process: CNC turning of case profile
  • Process: CNC milling of lugs and crown guards
  • Process: Caseback threading

Standards Reference

Standards: ASTM B348 Grade 5, annealed, 100% pressure tested to 1.25x rated depth, anodized finish
