I bought a BP 16710 last summer and recently have been wearing it more and more so I thought I'd check back at RWI and see what people are still thinking about this watch.
While people are free to like/not like what they want, and are free to mod anything they don't like, I think I'm a realist when it comes to these types of watches. If I want perfection I will buy the real thing. I owned a genuine 16710 but sold it because it wasn't getting enough wrist time compared to its value. On the plus side I made good money on that sale since I bought around 2017 and sold in late 2021 at pretty much the height of the market.
But by last summer I was wanting a Pepsi on my wrist again (at least part of the time) and picked up the BP 16710. I made a couple of changes. I bought the slimmer caseback which has reduced the thickness to 12.4mm. Although it's still slightly thick compared to gen, it's more than close enough for me. If I recall correctly the out of the box thickness is something like 13.2mm which was a hard no from me.
I also replaced the bezel insert as BP came with one a bit too purple-ish for my tastes. I added one from wholesaleoutlet990 from ebay. I think I'm going to get a couple more and experiment with bleaching one to take off some of the shine and fade the colors just a touch.
I also added hollow end links since I prefer the more old-school look. I realize the lugs should be drilled to have hollow end links but I don't care. I did the same thing with my genuine 16710 simply because I like it that way.
My BP came with the SA3186 so I also ordered a VR3186 on aliexpress. However, I've had no issues so far with the SA3186. In fact, I've regulated it to achieve a pretty consistent +2 or +3 seconds a day. I own a genuine 16610 that is not that accurate! If the SA3186 does break down I'll just pop in the VR3186.
With regard to the crown guards and lug chamfers, they don't bother me in the least.
Overall, I'm very happy with the BP 16170.
