Seiko 6105-8009 vs. Doxa 300 Searambler

Key Points from the Discussion

• When looking for a vintage Seiko 6105, prioritize original dials and hands, but note that unlike Rolex, there's more latitude for variations without significant consequence. The 'turtle' cushion case is the most common and features a crown-protecting shoulder, while earlier 'proof-proof' and 'resist-resist' models have thinner cases.
• The original Doxa 300 'no T' also featured a thin case, distinguishing it from the later, thicker Doxa 300T models.
• A personal anecdote highlights the longevity of vintage Seiko watches, with a Sea Lion from 1966 passed down through generations, though it eventually required servicing for winding system wear.
• A collector inquired about key considerations when acquiring a used Seiko 6105, specifically asking what to look out for.
• Historical pricing data shows a 1965 Seiko 62MAS retailed for approximately 13,000 yen (around $45 in 1975), while a 1967 Rolex 5513 was $160, and a 1968 Doxa 300 was $165, offering 300 meters of water resistance for a comparable or lower price than the Rolex's 200 meters.
• The market for vintage sports models has significantly increased in price over the past 3-5 years due to rising demand.
