## Total Performance Score (TPS): 4.0

## Collection Type by Style
- Adventure/Field/Tool: 100% (dominant across all, with Alpinist leading)
- Diver: 33% (62MAS)
- Pilot: 33% (Longines Spirit)
## Collection Type by Movement
- Automatic Mechanical: 100% (Seiko 6R35 x2 at 21,600 vph / 70hr PR; Longines L888.4 COSC at 25,200 vph / 72hr PR)
## Collection Strengths
- Exceptional historical resonance and design details from Seiko reissues paired with Longines refinement.
- Uniformly high build quality, water resistance (100-200m), and power reserves for reliable daily rotation.
- Strong value cohesion in a compact, thematic set ideal for active collectors.
## Ideas for Improvement
1. Incorporate a GMT complication (e.g., Zulu Time variant) to expand travel functionality.
2. Add a slimmer dress or racing watch to broaden style versatility beyond tools.
3. Diversify with a microbrand or higher-beat movement for added enthusiast intrigue.
## Downsizing Advice
To two watches, prioritize the two Seikos for pure thematic strength, historical value, and unbeatable bang-for-buck, selling the Longines if budget-constrained—though retaining Spirit + Alpinist preserves brand/Swiss balance.
