NH35 Movement:

The accuracy of caliber NH35/4R35 is between +45 / -35 seconds per day. This rating is based on normal daily wear on the wrist in temperatures between 5 ºC and 35 ºC. When testing your watch for timekeeping, make sure it is fully wound.


It's a Seiko 62MAS homage and the brand name Cronos logo inspired by the 1950s Seiko Cronos watches.


I bought it because I was looking for an affordable watch with good lume. This watch is the same as the ILW watch in this video below

Nice, looks a good patina.

I've got an Armida A1 on the way, was thinking of doing the boiled egg trick to accelerate the patina. Will post some pics when I get it and the forced patina.

Thanks Raymond,I'd love to see it when you do. I saw this article about aging bronze watches:
