Sudden slowing?

[gerry100]

Explorer II 16570 M serial, so assume 3186 movement.

Bought in March 2021 with a full Certified service from an AD.

Until the last few weeks, I've been keeping accuracy within 2 secs ( checked with IPhone) by regulating with overnight rest position ( dial up gain/on crown lose).

Knocked down by Omicron for a few weeks, back to 95% activity level now.

Checked accuracy 5 days ago and 15 seconds slow! Suspected Omicron inactivity so gave it a wind and reset the seconds. Resting face up at night.

Still losing a second a day (approximately).

Will wind and reset now, Thanks in advance for knowledgeable inputs
