@tomh207 Thanks! I am going to have a whack at this.

Just took a closer look, and it looks like the pinion is not through the jewel at all, if this is the case then the pallet fork may be completely pinched between the main plate and the pallet bridge, IF this is the case you will be VERY lucky if this has not fatally damaged your pallet fork! Hopefully this is a camera trick and not the reality.

Can we hav a better picture of the pallet jewels and their interaction with the escape wheel? The lads above have you on the right track but to back up - you wound it up a bit but is it sufficient to get things moving? The seikos are low amplitude and sometimes they need more incentive…

You may want to check out the end-shake on the pallet fork, switching parts, even from compatible movements can result in bridges pinching wheels and in this case (perhaps) the pallet fork. Another option is that the jewel in the pallet bridge is damaged (cracked) or maybe the pinion of the fork itself is damaged (bent, sheared, corrosion etc...) such damage may also prevent the free movement of the pallet fork. To check the end shake, use an oiler to carefully see if the pallet fork can move up and down (not side to side) between the two jewels, there should be a little bit of free movement up and down which is known as end shake. If there is movement then you can scratch this off your list of possible culprits, if there is no or very little movement then the bridge may be restricting (pinching) the pallet fork and you may need to move a jewel to allow sufficient end shake. I just noticed on your photo that I do not see the pinion of the pallet fork poking through the jewel, usually you can just see it poking through the hole in the jewel - maybe this is a trick of the light in your photo or some other camera trickery? However, this would lead me to think that there may be a problem with the pallet fork pinions, perhaps one or both is sheared off or otherwise damaged? @RichardHarris123 snap!

The exit jewel looks very deep into the escapement. To much lock?
