Is having a stainless sub too similar to a gmt BLNR?

[Rollieo]

I have a GMT BLNR on jubilee. I’ve thought about getting a stainless sub (not sure which one yet, no date, or date black or date green). I feel like the stainless sub is a great go anywhere do anything watch.

I’ve always felt design wise these two are too similar to both have in my collection though. I think the jubilee vs oyster is really the only major design difference, with of course a functional difference of GMT vs timer bezel.

Been on the fence for a long time on whether there’s room in my collection for a stainless sub given the similarities.

What do you think? Are these watches too similar to have both?
