Have you ever known a more versatile and widely used movement then the Miyota caliber by Citizen? There are so many watches using this movement it seems like the default movement for any watchmaker creating an accurate, reliable, and super affordable timepiece.

I just bought Ingersol I02802 the Apsley and it is equipped with this movement from Miyota cal. 8217 after three days on my hand (also overnight) it gained 18 secs. against the atomic watch – amazing.

I also have an Ingersoll but it has a Chinese Seagull style automatic movement. I didn’t know you could get a Miyota in an Ingersoll. The will totally take their brand to the next level imho.

I have the Bering 16243-462 with this movement only a 15sec gain in a 48 hr period and power reserve is accurate as well 41 has last time I left the watch without moving it.

My Boldr Wayfarer Khaki uses this movement. The rotor’s movement is very audible in daily life. It may bother some, but for me it adds a bit of character and serves as a reminder that I’m wearing a very sophisticated piece of machinery on my wrist.
