Yeah the 70 hour thing is of little use to the day to day user.
After all, 48 hours was more than adequate in terms of practicality.
That's one of the reasons why I believe Rolex was caught with their pants down in the battle for market supremisy by a major competitor who shall remain nameless but has gone down the twin Spring barrel path.
Rolex probably had to rush their design to market
