What the research found
These are the research’s judgments, scored against Holden’s priorities, not his own words.
Strengths
- Master Chronometer 8800/8900 engineering: METAS certification, 15,000 gauss, 0/+5 s/day [3]
- Genuine design story - 1948 Seamaster lineage, sailboat wedge indexes, teak-deck dial [4]
- Two case sizes and a deep dial palette allow precise configuration to taste [1][3]
Weaknesses
- Butterfly clasp lacks on-the-fly micro-adjust; half-links only [3]
- 41mm measured at 13.6mm thick - meaningful for a non-diver [7]
- 117+ references risk catalog dilution and weaken any single reference's identity [3]
- Price has climbed: $6,300 (2024) to $7,100 (2026) at retail for steel on bracelet [3][6]

| Value at a realistic price | 6.9 |
