The Constellation Deluxe makes a much more daily wearable piece, the downside to the Seamaster Piepan date at six models is there's no way to quickset them, and they're bumper automatics. This means every time you wear it, you have to manually set the date by winding the time forward (sometimes 30 whole revolutions).
You also can't keep it on a winder since bumpers don't wind on them, which means the only alternative to setting it manually is wearing it or winding it daily.
The Constellation on the other hand with no date means you never have to worry about setting the date, just wind it up, set the time and you're away.
