This is my SPB155J1 or also known as the Baby Alpinist. I know there’s a lot of love for the “Original Alpinist” and it’s internal rotating compass etc. Personally I found it too busy and too distracting from the actual dial.
I bought this watch for the dial and also the 72 hr power reserve.
I have some thoughts on this watch after about a year of owning it!
Pros
-
It has a beautiful fume dial that I absolutely adore. Seriously, in person it’s astounding.
-
The 38mm case diameter makes it a dream to wear on my 6.4 inch wrist and I would recommend it to most people with smaller - mid sized wrists.
-
This is my own personal caveat and that is I attached this watch to the first trip I took with my current girlfriend who I will one day make my wife so this watch is never leaving me. I named it Ionah which is Hà Nội spelled backwards which is where we took our first trip.
Cons
-
The 6R35 movement is terrible at timekeeping. It varies between being 15 seconds slow or 30+ seconds slow depending on how I set the watch in it’s resting position. Having read that Seiko underpromises and overdelivers on movements I was quite disappointed
-
It is a Top Heavy watch with minimal micro adjust. Even with the points of micro adjust I wasn’t able to get the perfect fit on it and I live in a country where temperatures are high and I’m more often than not in an air conditioned room so my wrist swells and contracts so that sucks.
-
Lume is meh
-
Retail price imo is definitely on the higher side and I would recommend buying it pre-owned
Conclusion:
A robust watch with lots of character but is lacking in terms of precision and accuracy.
6.5/10
I hear you on the accuracy. I've started regulating my seikos that run too slow or fast. Just did one yesterday, was +35 now it's around +4
You mind explaining how you went about it!
