This is the only watch that I bought in all of 2009, and my first Patek Philippe watch. I have long liked the 5059, but did not find its dimension to be ideal. The 5159G has all the attributes that I want - perpetual calendar, officer's case with hunter back, retrograde date, 38mm. Thank you all for the valuable knowledge I have gained in this forum, that helped me make this wonderful decision.
Cheers,
CS
