These are the two 46mm in diameter new models (the chronos are 44mm and that regular Automatics are 42mm).
First, the 2000:
It has a really nice dial, and again the appendage at 9 o'clock is not a helium release valve. These watches can withstand the pressures of great depth without such a valve. However, one deficit of this is that the watch is relatively high: if I recall, it's a fraction over 17mm. The case is titanium and comfortable as a result.
The Deep Three really looks nice:
It is also comfortable given its titanium case. It is water resistant to 10 bar (about 100 meters) which is deep enough for virtually all amateur diving. The Deep Three uses the same basic mechanism as the Deep Two, but with some technical improvements.
