accutron caseback restoration
Hi, I'm a collector of accutron 214's as you can tell by my name here. I collect stainless steel watches only and do my own case disassembely and polishing. But I want to know how to correctly re grain the caseback and setting crown/battery hatch to a accutron 214. I have asked this question in other forums and have gotten partial answers mostly wrong ones. They tell me to regrain the flat of the caseback by sliding it in a line on a sheet of sand paper. So I bought a couple junk backs to try out and it didnt look like the graining on the backs of watches I have sent out to a specialist. Those backs look like it was done on a brush finish wheel. Can anyone tell me how to achieve the correct look and the tools i need to get/use. Iknow I can certainly do it correctly if someone doesnt try to keep this knowledge secret

AP ROO Bracelet and Case comfort
So I'm finally going to do it. Probably sending money today.Im pulling a trigger on a AP ROO on a bracelet (42mm). I have a 6.5 wrist. My biggest concern is comfort. I own a 44mm PAM 359 with a 50s case, its hard for me to wear due to its very uncomfortable imo. Does the AP ROO wear similarly to that PAM i don't want to buy such a big watch and end up hating it.I know a 39mm option is out there for AP but not really into that right now. Im just focused on the AP ROO 42mm at the moment.Any info on comfort of the 42mm AP ROO on a bracelet is greatly appriciated.

Nautilus Strap Conversion Kit
The question has been asked many a time and oft and the answer is always negative, but I'm just sitting here looking at my 5711 and I just can't understand why some budding entrepreneur hasn't created a conversion kit for bracelet-to-strap conversions for the Nautilus. The bracelet, including the end-link is attached by pins to the case. Surely all it would take is the fashioning of an aftermarket end link to fill that gap and with another hole through it to allow a strap to be secured to it, in the same way people make after-market plot links for AP's. I'm not suggesting for a second its something I could do, but there are so many people out there that could, I'm surprised someone hasn't given it a bash. They've managed for Audemars, Rolex, etc. it's not like the Nautilus hasn't been around a while...It's not like your typical Patek owner is strapped for cash so I'd think the producer of a decent kit could charge like the proverbial rhino.Just a thought...

Unworn Condition/ Protective Plastics in place
Does this mean that the watch is BNIB?This is not to offend anyone. I'm looking at some of the watches on the internet and see this a lot. I'm looking for a specific model but want to make sure that it's a new and not used by someone with plastic still on.Thanks

Nice shot
Hi guysI'm in love with the 16710 right now and keen on pulling the trigger on one. Already have a few other models with Swiss made dial so wondering if I should go for the tritium dial and hope that it'll age to a nice patina or just go for a newer piece with the Swiss made dial. I'm a newbie here and hope to get some advice on this. Any thoughts? Tks in advance.
