1. Sub is a great watch and very versatile.
2. See if you can get on a waiting list for either/ both gmt’s
3. You may well have a long wait, plenty of time to think about it.
4. When one comes up, buy it but keep the sub, at least for a while so you can truly make your mind up, or just keep both.
5. You are likely to be able to sell one of them if you choose, without taking any hit (possibly a profit), particularly if you have bought at rrp, rather than via grey.
6. Don’t be in a rush. Enjoy the sub in the meantime.
