Omega Speedmaster vs Seamaster: which to buy pre-loved?
The Speedmaster is Omega's chronograph, famous as the Moonwatch; the classic Professional is hand-wound, with a tachymeter bezel. The Seamaster is its dive line, led by the Diver 300M: automatic, water-resistant to 300 m and famous on James Bond's wrist. Choose the Speedmaster for history and a chronograph, the Seamaster for a tougher everyday watch.

Omega Speedmaster vs Seamaster: questions
Can I swim with a Speedmaster?
The Moonwatch is rated to 50 m, so it's not the watch for swimming; the Seamaster Diver 300M is.
Hesalite or sapphire Moonwatch?
Hesalite is the flight-qualified original and scratches easily but can be polished; sapphire resists scratches.
Which Seamaster should I look at?
The Diver 300M is the classic; the Planet Ocean is bigger and deeper-rated, and the Aqua Terra is dressier.
