I can't speak for the JSAR but I own a TSAR and it has been very reliable. I have heard however, and experienced this myself, that the markings on the bezel are not so sturdy, my time start triangle fell out a few weeks ago, see picture. But the tritium light source and overall build quality is IMO worth the money.

My GSAR has been pretty nice. I did have to have the crown stem repaired, though. The threads stripped out. Other than that, I've had no issues with it at all. Very reliable. Accurate to +1 sec a week.
The J-SAR is a very solid watch with the best bezel action i've seen or owned! The lume is as good as Seiko and so is the construction IMO. I have mine for about 5 years now and, even though it's never been abused, still ticking strong. No problem with lumed pip on mine (which i think was an issue on older G-SAR and SAR) On bracelet, that watch is very comfortable and for such a huge chunk of steel, is probably the most comfortable big watch I own.
i have had a tsar for about 7 years as a beater. I have fallen 9 feet onto hard wood floor landing on the watch hard and its still ticking fine. Its well made and of of my favorite watches ever. I like it so much since i beat the hell out of it. I just sent it away to get a new bezel because of major dents and case repolished to new.
I have/have had the JSAR, CSAR, TSAR and of course the SAR, which started me on buying these and is still my favourite Marathon.
I dont use my JSAR much, but quality is just fine.
In fact all my Marathons have worked well and the watches are excellent value for money.
