Known service issues
- No significant failure modes documented in its first decade of production; the 3235 is one of the most reliable calibers at any price
- Watch for aftermarket replacement springs: authorized Rolex springs are blue, unauthorized substitutes are often purple or uncolored; this affects resale and warranty status
- Factory-only service is strongly recommended; aftermarket service can void Superlative Chronometer designation and affects resale value
