Watches

Planning to buy my first real watch and I need your advice to choose the best option.

I intend to use this watch as the only one in the "collection" for a period of 2 to 3 years (Excluding a GShock for heavier activities), after this period I want to purchase an Omega SMP (One of my grails), so it needs to be a versatile watch for any occasion, both formal and casual., and cannot be a diver.

I`m not planning to sell this watch in the future, because it signifies a personal achievement that I'm going through at the moment, and it will have a permanent place in the collection!

What are your recommendations ?

(6.9 inch Wirst here) Thanks guys !
