Fuji GW690 Blank Frames

It may be from how you load the film. Makes sure the roll is tight at all times, and maintain tension on the film originating spool as you load/close the camera.

Thanks, I’ll try that. It produces stunning images when everything goes right.

Uneven spacing might not be a sign of a worn gear cog train, but of film slippage in the take-up spool. Depends on not only loading it correctly in the take-up roller, but sometimes the brand of film itself. Off-brand stuff might be squirrelly, so I stick with Kodak, Ilford, and Fuji. I admittedly don't have any experience with the early GW series, but do have plenty of experience with the later GW II and GW III.

I have a GS645 rangefinder. The film advance jammed and I had it repaired. A year later the mechanism broke again. Now, it always advances the film and cocks the shutter, but the exposure counter and double exposure prevention (DEP) do not work reliably; often the shutter won't fire because something's stuck in the DEP.
The point is, it is possible that a problem is surfacing with the mechanical film advance mechanism. It's complicated and hard to find parts for but I wish you the best of luck.

I've had no problems using Arista, Foma (same thing), Shanghai, Lomo.

Sometimes the width of the backing paper itself is off, and impeded efficient winding. Can't remember which specific films. But it's always a good idea when trying something different to waste a roll seeing how efficiently it spools before going out and shooting. Since I have several different MF camera bodies and backs with slightly different take-up mechanisms, I need to be certain a given film will work in them all.
