What is Professional Dive Watch Cases & Components?

⌚ Professional Dive Watch Cases & Components represents a complete system of precision titanium components engineered for Consumer Electronics applications. Large-diameter case body (>40mm) with crown guards, threaded crown tube, drilled lug holes, caseback threading, and bezel interface The system integrates 0 distinct component types manufactured through 3 specialized processes.

Engineering & 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.

Standards & Material Specifications

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

  • ⚠️ Deep-sea pressure resistance (1000m+)
  • ⚠️ Corrosion from saltwater and sweat
  • ⚠️ Hypoallergenic (skin contact)
  • ⚠️ Aesthetic surface finish
  • ⚠️ Thread galling of caseback

2 Material Selection Rationale

Grade 5 Ti-6Al-4V — General alpha-beta alloy, high strength

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.

3 Form Selection Rationale

Round Bar / Rod — for turning, fasteners

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.

4 Manufacturing Process & Services

Core Processes:

CNC turning of case profileCNC milling of lugs and crown guardsCaseback threadingBead blasting / anodizing / PVD

Toll Processing Services:

Water pressure testing (to rated depth x 1.25 safety factor)Thread gauge inspectionSurface finish measurementMagnetic field testing

Process Pitfalls:

  • ⚠️ Caseback thread must be 10+ full turns with 0.5mm pitch for reliable sealing
  • ⚠️ Crown tube O-ring groove must have Ra<0.4um to prevent leakage over time
