First GMT I bought, Incorrect handstack from bklm, runs like a gem.
On the winder it keeps spot on time.
Second GMT CHS ceramic, it was a must have. What a POS lasted about a week, left on winder with BKLM gmt, and have a more accurate sundial in the dark.
Unable to adjust the GMT hand at all, Feels like something in the gears is missing. Maybe I am the unlucky one but it is the last 1 that I buy!
