Buying notes
- San Martin's following is narrower than Seiko's, so resale takes longer and prices swing more.
- Returns, warranty support and homage styling are the real risks to weigh, not the spec sheet.
- The Seiko is the safer buy; the San Martin is the better-specified one. Decide which matters more.
