Working on a deal for a SpeedyMoon 3575.20, unknown service history

Hello all,
As the title says, after seeing a few seemingly great quality examples lately, I’ve decided on picking up a white gold bezel 3575.20 speedymoon.

I found a solid listing I think, but I have a couple hesitations I’m looking for guidance on:
- No service history but the piece is “keeping great time” and prior owner “kept in his safe mostly”
- The included warranty card is blank, not filled out, but looks to be period correct for some I’ve seen with this reference (white)
- The red box is in a little rough shape, and the pusher tool is missing. Should this matter? I could get a replacement box for $100-150, yes? And I’m hoping an Ob could assist with providing a pusher tool.

The seller has agreed to take it to an OB or AD and have them remove the caseback to get a photo of the serial # on the movement, and also to just see if there’s anything obviously wrong. I’m not thrilled about a blank card, so I’m guessing this is the best way to address that? Should this have a large impact on price?

I’ve seen $750 for a service cost for this model, but how do most of you factor this into the cost of a piece you may be considering purchasing? Do you proactively do this on a 20-ish year old watch even if it is still “keeping good time.”

With no service history you should assume it will need to be serviced.

I try to factor that in on the price, but it really depends on the popularity of a particular model.

You can also take the watch into an Omega Botique and they will test and inspect. They will let you know if a service is recommended.

I don't think there is much value in getting a new box. It's pretty common for those boxes to flake. I don't think many care, in fact it it may be odd to have a new box with that older watch.

Great to know about the OB determining if service is recommended. I’ll ask that is determined when he stops in to have them take a photo of the movement. I’m assuming the “proof” to request in this case is a timegrapher report? I may ask to call the OB myself to verify their evaluation. Otherwise it’s seller’s word, and while I’d like to just trust it...

After much digging I found the prior listing and previous owner, and contacted them regarding the piece.
It was last serviced 10 years ago - based on everything I've read, it's due for a service now.

Doubt that anyone’s following this but the seller found a different buyer not put off by the servicing situation

So I guess I set my sights forward on finding another nice listing this time serviced and with Complete now with filled-out papers.

And pay more than I was going to here, for sure, but not with a near $1k service looming.
