Explorer I vs. Milgauss, help me pick a graduation watch!

[ramonesf2]

Hey everyone! I'm new to this forum, so I apologize if I'm posting in the wrong place. I'm looking for a watch to purchase for myself to commemorate my college graduation. I have a few nice watches (Tissot Visodate, Hamilton Navy Pioneer, vintage Longines, Nomos Tangente), but I want to buy my first "luxury watch." After going to different stores and boutiques I have narrowed my choices down to 3: Rolex Explorer 39mm, Rolex Milgauss (not sure on white dial or GV), and Omega Seamaster Aqua Terra Master Co-Axial 41.5mm. Ideally I would like my first luxury watch to have anti-magnetic properties since I am graduating with a bachelors and masters in electrical engineering. I want the anti-magnetic property because it relates to my field, rather than practically using it.

After going to the Rolex boutique, I found that the Milgauss and Explorer I are the only Rolex models that I like. I'm not a fan of the cyclops or the complications associated with the GMT and Submariner. I love the simplicity of the Explorer I and the Milgauss.

This brings me to my dilemma. If I get the Explorer, I won't want the Milgauss because I would prefer to diversify my collection rather than purchase multiple watches of the same brand. I would also purchase the Aqua Terra along with the Explorer because I do want a watch with anti-magnetic properties. Of course, this would be a lot more expensive than just purchasing the Milgauss. So should I save a little more money and purchase the Explorer and Aqua Terra, or kill two birds with one stone and purchase the Milgauss? If so, which Milgauss model would be the most versatile? Keep in mind, I have already tried on all of these watches and love how they look on my wrist.

Any input or opinions would be appreciated!
