Watch insurance in the UK

[j800ama]

Evening everyone,

I'm sure this question has been asked more than once on here but as insurance brokers change so do their prices.

I picked up my deepsea a few months ago but due to travelling / work / not using the watch, I had not found insurance. I did get a quote from Affinity insurers just over a month ago and they were in the region of £300 a year and just under if I took a three year policy so I thought i'd get in touch with them when I was next home. Fast forward to today, the new sum of £613 was required if I wanted one year with them. My previous quote was void as I was 6 days over the 30 price promise.
Can someone recommend an insurance that doesn't take the piss?

Cheers
