Opinions on PM models.

[Rockslide]

Need some opinions guys. Im looking into adding a PM yellow gold into my collection.

I currently have this in my collection
- Explorer I (214270 mkii)
- TT Submariner (116613LB)

The Explorer I is my daily on weekdays and I wear my TT sub on my offdays /weekends etc.
I have owned the BLNR, but traded it to the TT blue submariner as I have always loved the blue dial, and I love the look of yellow gold. Im now looking to step up to a full gold experience and im torn between the choices.

Im looking to add one of these
- Submariner 116618LB or LN
- GMT II 116718LN (black/green dial)
- Day Date 228238 (stick/romans)

I love the submariner, but will it be to redundant to have two blue dials. The black the dial is nice, but I cant stop thinking of the blue. It looks so good against yellow gold.
GMT II is nice as it sits a bit lower on the wrist than the sub, and the added GMT function. Im not so fan of the big numbers on the bezel compared to the sub.
The DD40 is the Rolex, the bracelet is beautiful and classy.

I want the watch to go with any occasion. Im not wearing suits regularly, but there will be times.
Enough of my rambling. I will be visiting my nearest AD and try on these when I have the chance, but in the meantime I would like to hear your guys opinions.
