This is a Spyderco Caly 3.5 in ZDP-189. Used just a couple of times, it still has the factory edge and comes with the original spyderco box and inserts

Not a lot of price comparisons for this in the UK market so I’m putting it at £90, but I’m open to negotiation

Payment by PayPal G&S, I’ve sold stuff on r/watchexchange and have an eBay store with 100% positive feedback

Paid straight away no issues, communicated clearly and an overall perfect experience

We all know that different positions affect how accurate a watch will be- for my daily, crown up will make it fast a few seconds a day, most other positions will make it slow a few seconds a day.

My question is, what causes this ?

I’ve had a Tudor Day-Date for about two months now, and for all of those two months up until a few days ago, it has been running at a solid +1/2 seconds a day. However over the past few days, I’ve noticed it is running more like -6 seconds a day. I’ve checked both on the wrist and in my watchbox, all readings have been about 5/6 seconds a day slow

I know 5 seconds a day is well within the tolerances and in itself not something to be worried about, it’s more the sudden change that has me concerned, and the prospect that it might continue getting worse. For reference the Tudor was bought new and well within warranty and all that.

What do you guys think ?
