To Flip, or Not to Flip?

[Spoonage]

I own both. The BLNR was my first then I got the SubC. The GMT function is a very handy complication and I use it often. I travel a ton for work and have multi country project meetings and while I can figure out the times without it, it's great to be able to track several timezones. I for sure use that more than 300M water resistance. With that being said I do use the timing bezel on the SubC.

It's always a hard choice, but for me I always recommend to add and not replace. They truly are a great pair and between the two the BLNR gets more wrist action, but it sounds like you don't need the GMT function. I would let it ride for a bit and in a few months when you have a bit more saved, see if you still want the BLNR and then add it.
