If it doesn't hurt financially, and it balances with getting wrist time along with your other watches (as opposed to relegating a watch to a watch box) then go for it!
It seems there are roughly three different camps in watch enthusiasts, at least from what I read here in watch crunch and elsewhere. Those that stick strictly to a small collection of no more than 4-5 watches or less. Those that have 6 to 14 and have a "one in, one out" rule to keep things balanced. And those that collect for collecting sake and don't mind if 20 watches (or more) stay in a box(es) most of the time.
The perils of well made inexpensive watches are real man!
I like to imagine I'll be in the first group someday, lol. But the reality is that I'm in the 2nd group struggling not to be in the 3rd group and having to justify my "hobby" to my partner when we have so much expensive sh%t to do around our house.
Sound like you are in the enviable (to me) first group at the moment. Hope you can stay there lol!
And lastly I love that Zenith, great looking watch that seems like it would do really well with different straps!
My Christopher Ward Sealander bracelet was a revelation for the same reason! Being able to quickly adjust anywhere, anytime throughout the day has been amazing and hard to wear other bracelets now for that reason! To me it's worth coughing up the extra dough re mi to have that flexibility. Dug your explorer vid by the way!
