if i were you, i would definitely not take the top gun double chrono because:
1. its size is not right (46mm) relative to its little brother the regular top gun chrono;
2. it's made in large quantities and much more readily available than the top gun chrono; and
3. it's considerably more expensive.
292 in this case for sure.
but if we're considering the regular top gun ceramic chrono, then it's a much tougher call. the 292 costs around US1500 more based on each's respective street price. i had a 292 before and still have the top gun chrono. if i were to make a choice again now, i would take the 292 because i wore that much more than the top gun, even though the top gun is a more "practical" watch in the sense that it gives one the impression that it's a tougher watch for daily wear.
