In 1962 a GS sold for 300,000 to 400,000 JPY according to Seiya https://www.seiyajapan.com/pages/the-hi ... rand-seiko
Go here and convert it to see what the actual value conversion was back thenhttp://fxtop.com/en/currency-converter- ... tnOK=Go%21
I used 350,000 to go in the middle and I got $972.22 for a 1962 conversion.
So, in 1962 it cost $972.00 to buy a GS, not in today's money.... $972.00 at that time.
Today that GS is around $2,500.00 to $3,000.00.
Before Photobucket took a dive, I had pictures of a guy selling his Rolex in 2015 for $29,000.00. It had originally been bought for $265.00 at a military PX in 1964.
I love the GS, I am a huge fan, but it is clear that as an investment Rolex wins and wins big.
A GS in 1962 would a little more than double and maybe triple your money.
A Rolex in 1962 sold for a hundred times the original price.
Given that I'm a fence sitter in these sort of things there's advantages and disadvantages to each. And sometimes what some consider a disadvantage is actually an advantage from a different perspective.
Rolex as an investment - no argument. But the Seiko is purchased when stocks or gold were obvious alternatives. You can't wear a mutual fund but you can wear gold if so inclined. And even watches that are passable investments are like classic cars - there's some depreciation when purchased new that eventually turns into appreciation like an inverted bell curve.
Prestige = Rolex. But not necessarily exclusivity; they do crank out about a million a year.
Some people seriously don't like being noticed. To those people a Grand Seiko offers a very nice watch that will never once be considered ostentatious. This is where the ubiquitous name works to its favor. If you prefer to have people think you spent a wad on your watch then Grand Seiko probably isn't a good choice.
Technology - definitely GS and it has the side effect of shopping for a used spring drive as safe as being in your mama's arms. Nobody has managed to clone it. Shopping for a used Rolex is a mine field requiring expertise to navigate the shoals lest one spend Rolex type money on a fake.
Heirloom = Rolex. GS doesn't even guarantee parts availability past ten years.
Finish = GS. Buy a GS and you'll find yourself buying a 20X loupe. The closer you look the more detail becomes apparent.
Sometimes you want a prestige product that can be serviced generations into the future that increases in value. Other times you just want the best finished watch you can get your hands on that can be worn anywhere and will be assumed to be a 300.00 Seiko by 99.9% of the population.
They appeal for different reasons but not necessarily different people.
GS owners may have a minor advantage in that they sometimes have less of their ego tied up in the product. They will cheerfully acknowledge those areas where Rolex has an advantage. Finding a Rolex guy willing to fess up that GS has superior tech and finish is a bit more challenging of a search on average. Strangely they both agree that the GS says Seiko on the dial - one doesn't think it makes for a proper watch while the other either doesn't care or actually prefers it.
Those with both don't understand what the debate is all about. I'm more into GS than Rolex at present but Rolex may catch up. To me there's not much incentive to keep buying GS as they tend to be similar to each other - I can't picture more than a half dozen if I had both the money and time. There's a bazillion versions of Rolex offering multiple specializations to collectors.
On the other hand I would wager that GS never undergoes the benign indignities that a Bamford would inflict on it. That took a different breed of Rolex cat altogether - fortunately very limited in their numbers.
