The question of whether the SPBX 62MAS “reimagination” models are worthwhile or not seems extremely subjective.
I’ve owned two, the 143 and 149, along with the SLA037.
The 149 is a great value, from my perspective, in terms of the beautiful color on the dial, PR, diashield coating, bracelet, and silicone strap combo, etc., and the timekeeping specs of the 6R35 relative to the cost. I rotate so often I never bothered to track the timekeeping performance, but it seemed fine. Mine wasn’t getting wrist time, since the SLA037 and others were hogging it, so I happily moved it along to a new home.
I think the bracelet is fine for the cost, but have read some complaints others have about it. Regardless of its relative value, I wasn’t wearing it on my 143, never even had it sized, so I moved the still-stickered bracelet along to a happy new owner as well, who is enjoying it. To each their own.
I have owned a number of Black Bays, including the BB58. All things being equal, I don’t think the finishing of the SPB14X models is close to that of the 58, nor is the movement chronometer grade like the 58’s...but all things are not equal, and the BB58’s significantly more expensive.
If one were to compare the finishing on the 58 vs the SLA037, that may be a more fair comparison, and the SLA037 may win out, in some folks’ opinions. But again, the comparison wouldn’t be made in a vacuum, and the 037 is twice the cost of BB58 on strap or thereabouts, so that’s a huge factor for many of us.
Bottom line, I think the SPB143 at its cost works for me as a versatile, tough change-of-pace watch on a variety of straps, but I get why it might not work universally for everyone. I’d also not personally ditch certain others I own in favor of keeping the 143, if forced to pick, but to each their own.
I like the SPB14X line, and for me, they’re solid value.
