I have narrowed down my next watch to:
1. New Tudor Black Bay with the in house movement (70hr power reserve).

Or

2. Grand Seiko GMT SBGE015. Made of titanium with the spring drive movement and 72hr power reserve.

I am torn between the two! In my head the Grand Seiko probably steals it but the Tudor will be significantly cheaper at £2510 vs around £3900 for the GS!

Thoughts most welcome!
