Kirium: Repair or sell for spares?

So, I took my Kirium Professional 200M, model WL111F, for a battery replacement last week (it's been sat in a drawer for 5 years), and was told the old battery had leaked. I've had three repair quotes, between £205 to £345. The case and the bracelet are in really good condition, almost as new, and I have all the paperwork, case and box. I'm probably going to sell it, and I'm trying to work out whether it's best to go ahead with the repair first or just put it on eBay as spares or repair. Any thoughts?

It might even be worth breaking it up and selling the bracelet and the case separately to get the most money.

Thanks....here's what it looks like. I love the look, but it never felt comfortable to wear

Really? I've always found the Kirium one of the most comfortable watches on wrist...

I don't do well with heavier, thicker watches full stop, I never get used to the extra weight and bulk on the wrist. Currently I use a Skagen, but eying up a Citizen Eco-Drive One...
