Seiko mods are great, if you see one you like go for it
I modded all my Orients, at minimum replaced the crystal with sapphire like the Kamasu. The Ray2 and UnoMako I did crystal, bezel and bezel inserts. Swapping out the bezel insert will give you that fresh watch feeling!! Had a few more but the Nephews got those for Christmas.
Some of them are brilliant, haven't pulled the trigger on one yet,but like you I'm interested. (Don't take no notice of this lot they probably have no taste unlike us (well you))
Mods have been frowned upon because they move a piece from "ALL ORIGINAL PARTS!" to "some rando thought this change looked better than the actual designer". This also introduces the potential for frankenwatches to be sold as the real deal.
The Seiko models being modded will likely never achieve the same level of collectability as vintage pieces like a Hamilton or a Waltham since society has now deemed everything new as potentially collectible and so we save them all in as good of condition as we can; creating a glut of availability.
I say do what you want to your watch. If I get enough people to mod their watches, my NIB <insert model here> will be worth millions!
If you Love your Mod That’s All That Matters!!! Many of my Vintage watches Do Not have original crystals or watch bands . In essence, the are MODS !!! 😉enjoy!
Seiko Mods should be outlawed. They are addicting, and their components come through questionable supply chains into our country. Once hooked, the victims are usually unable to stop, and rely on more mods at a faster rate to satisfy their modding urges. 😉
Just a guy with expensive hobby.
