New Sinn U1 - A tale of woe

[Olivera]

I mentioned this on the Sinn thread, but thought I'd spin out to here.

So I ordered a Sinn U1 SDR with Tegiment (Sellita SW-200-1 Top Grade movement) in Feb, it arrived at the AD in Mar, I then picked it up.

Straight away it ran significantly slow, from 1-2 minutes per day. Spoke to the AD and they stated to give it a while to 'bed in'. So I did that and it got no better. I then took the watch to a repairer for a magnetisation test and to see if there were any observable faults. He reported the timing was shot when placed face down or on it's side. I returned the watch to the AD, and it was sent back to Sinn (or their UK service centre, I'm not sure which) for repair.

I received the watch back 2-3 weeks ago, and the AD stated that it had been re-regulated. It's timing is significantly better, but I've now noticed that the power reserve is shockingly bad. It has stopped on a couple of occasions in the morning after at most 10 hours off my wrist. Note I've been active every day with at least 35 minutes of walking. I again went to the watch repairer and he stated that it's amplitude is low (220 degrees?), which might account for the extremely low power reserve.

So, what the hell is going on with this watch? Is it just a defective Sellita movement? Why is Sinn's QC so bad? I'll likely be returning to the AD soon, but thought this was worth sharing.

Try winding the crown around 30/40 and see what the amplitude should be around 290 ish

It may well be a faulty movement, but I found Sinn to be a waste of time for customer service. I would just ask the dealer for a refund or exchange. I'd never buy another one after having a U50 that made several trips to the service centre.

The watch repairer did that prior to testing the amplitude, then reported 220 degrees.

I'm currently leaning towards insisting for a full refund. I've thoroughly lost trust in their ability to deliver a working watch sans issues.

You must have a faulty movement - I will have had my Sinn 104 (which has the same Sellita top grade movement) for a year next month and I've been genuinely staggered by it's accuracy - only had to adjust it a handful of times. I would also send back for a full refund or exchange.
