A lot depends on your wrist size. The standard Datejust is 36 mm. The Date model you chose is 34 mm. There is also a Datejust II that is 41 mm (link:
http://www.rolex.com/en#/rolex-watches/datejust/datejustii-41mm-rolesor-m116334-0001 ). This watch is more or less the same size as the Professional models such as the Submariner.
If you have a regular wrist size go with the 36 mm. If you are big go with the D-J II. If you have smaller wrists, go with the 34 mm date.
Keep in mind that there are 20+ regular dials/faces (index, Roman numerals, Arabic numerals etc. in different colours) available for each of these models. A different dial will create a very different look.
The Date model only comes with the Oyster bracelet as shown (from memory) while the Datejust models come with either the Jubilee bracelet (as shown) or with the Oyster bracelet.
In any event, you will want to go to a retailer who has a large selection so you can see the same model with different dials.
Based on your choice of model, you should be able to get the CH and UK price and do your calculation from there. When importing the watch into CH you will need to pay the VAT (8% as of Jan 1.) and a small % duty.
Happy shopping.
