Rechecking ISS spacewalk & onboard photographs, we can conclude Konstantin Chaykin were certainly wore during these events:

2021, April 9
Taken to the ISS onboard Soyuz MS-18 by cosmonaut Oleg Novitsky
2021, September 3
Worn over red-striped Orlan MKS n° 5 space suit during spacewalk : 7 hours 54 minutes
2022, April 18
Worn over Blue-striped Orlan MKS n° 4 space suit by Denis Matveyev : 6 hours 37 minutes
Worn over Red-striped Orlan MKS n° 5 space suit by Olega Artemyev : 6 hours 37 minutes
2022, April 28
Worn over Red-striped Orlan MKS n° 5 space suit by Olega Artemyev : 7 hours 42 minutes
2022, August 17

Onboard the ISS both large Konstantin Chaykin chronographs can be seen strapped over the left forearm of the Orlan MKS Spacesuits in storage.

Thus far 12 different brands have been used during EVA, recently some inexpensive Russian wrist watches but even the famous X-33 has been worn outside ISS.
Several space agency logo watches have been spotted (Roscosmos logo Konstantin Chaykin and an Energia logo watch with Russian Fed logo).
Cosmonauts taking opportunity to wear a maximum watches as space-flown souvenirs for family and friends!

Watches seem more like souvenirs than tools when three are worn at once for an EVA… I can’t blame the cosmonaut for doing so (how cool would it be to own one!), but it takes even more shine off of the watch’s role in space these days.

The 3861 has still not made an appearance for an EVA as far as I can tell. I am under the impression an American hasn’t worn a watch for a space walk since 1993; if one suddenly did don a 3861 for an EVA, though, would it still need to be hesalite? I don't believe NASA has changed their stance on this, but I also see sapphire crystals aplenty on astronauts these days (albeit inside the spacecraft). Does anyone know when NASA began to allow sapphire crystals in any capacity?

I understand Russian cosmonauts are the most recent wearers of the Speedmaster, and they’ve worn watches with sapphire crystals for EVAs, so maybe when a 3861 does appear in space, it will be on a sapphire crystal. :🍿:
