the ring can be pried out, probably gunked up which is preventing it from 'feeling' like it wants to come out but it will. t

This is the type of tool that I use. http://www.ebay.co.uk/itm/Deluxe-CASE-OPENER-snap-on-case-back-tool-repairs-NEW-watchmakers-repairs-tool-/201070646748?pt=UK_Jewellery_Watches_WatchAccessories_SpareParts_SM&hash=item2ed0be95dc https://www.cousinsuk.com/catalog/tools/snap-on-case-openers/case-back-tool-watch-snap-on-openers-bench-top

As Will says, it comes out the front when you remove the bezel complete with crystal still in place. If you look very carefully, you should find a section of the joint has a very small slot to allow a knife to be used to pry off the bezel. Be very careful if using a hand held knife because as the bezel pops off you may follow through and damage the hands and dial. You can purchase a bezel removing tool that makes the job safer.

Looks as though you might have to remove the bezel - some watches are front-loaders!

What i did was use an old mineral glass (easy too see how much oil has flowed) to practice on and kept adjusting the oiler until I got a sensible flow.
