路My PADI turtle was -1.7 for all of 2017, then last year it started running -25. My Blue Lagoon LE turtle did the same darn thing, -2 sec/day for the first year in 2017, then dropped to -45 sec/day in 2018.
So I put them away until I had time to take them to my watchmaker to have them looked at, then forgot about it.
Perhaps as simple as getting it de magnetized. No exotic materials here.
