Sheared off attachment tube in second hand - how to remove the remnant?

Hi,

I've never successfully disassembled and reassembled a movement before!

So I removed the hands from a watch that I was working on before.  After fitting back the dial, plastic spacer, etc, I discovered that the second hand couldn't be attached to the second hand gear shaft (sorry, I don't know what the correct name is).  It kept falling off. 

On close inspection, I realised that when I removed the hands, I accidentally sheared off the "tube" that holds the second hand onto the second hand gear shaft.  Now there's a remnant stuck onto the second hand gear shaft.

Short of dismantling the movement (I probably can't put it back together), is there any tool/technique to pull out the stuck tube?  For now, the watch shows only the minutes and hours ?

thx!

Pivot. Have a read of the topic below. Also,  iwith almost all questions is useful to post pictures.

For a sure grip you would need to pull from below the tube, but that is not accessible. Removing plate, hour wheel and cannon pinion only may or may not help. You can try with sturdy tweezers however.

It sounds to me as if you have pulled the hand off but the tube is still on the pivot. You will need to remove the hands and dial. Use some tool to get below the tube and pull. this should do it. It's a pair of hairspring cutting tweezers with these you can get underneath the tube and pull upwards make sure you pull up straight.

      School Me Please: Sliding Mainspring Bridles

      This is the old/first(?) way for making a mainspring for an automatic. "Evolution-wise" it is an logical first step forward from a standard spring. Usually these are indeed replaced with a new spring with an integrated/fixed bridle. Lubrication as you would do with any automatic.

      Unknown watch movement logo. Very interesting

      Thank you. I was informed it was a cheap worthless Lack watch from India. It’s in a small mens watch looks to be around 1930 odd   Cleaned the movement and it’s going really well. Keeps good time.  This is a great site. Mystery solved. I’m obliged.

      I'm working on a Schild AS 1250 (a 'bumper' automatic) and it's the first time I've seen a mainspring like this. It has what looks like a regular manual-wind mainspring with a 'hook' at its outer extremity. On a manual-wind watch that 'hook' would engage with a 'hook' in the barrel wall to prevent it from rotating. However, the AS 1250's mainspring does not engage directly with the barrel but rather with a 'sliding bridle' that sits between the mainspring and the barrel wall, and evidently facilitates the slip necessary in an automatic. I'm not sure what advantage this two-piece configuration provides, but it highlights a gap (one of many) in my horological knowledge. I'm not sure if 'hook' is the correct term as used above, but please see photo below to see what I mean. Therefore, two questions please. 1. What is the proper way to lubricate a barrel from an automatic watch with a sliding bridle? My guess is the same as any automatic ms/barrel (e.g, a few dabs of braking grease on the interior barrel wall). What do the experts say? 2. I purchased a Generale Ressorts GR3472X mainspring, made for the AS 1250. It looks like the bridle is included and I don't need to salvage and re-use the old one. Is this a safe assumption? Thanks for the advice. If you have any other wisdom you'd like to share about separate sliding mainspring bridles, I would be very interested. Cheers!
