First of all, these watches.
A must-have tank that arrived yesterday and today.
Both are LM size, classic ivory Roman, and come with a lifetime warranty.
However, I can still call it a "miracle"...
Actually, even though this is the same mast tank, the machinery inside is different!





The right one is hand-wound and the left one is quartz.
I have sold the hand-wound must-have tank with a lifetime warranty several times, but
This is actually the first time we have received a quartz mast tank.
I mean…
This is the first time I've heard of a quartz mast tank that comes with a lifetime warranty.

I have confirmed that the lifetime warranty lasts until the mid-1980s.
After that, I have seen half-price tickets for complete services and free BT exchange tickets.
It is surprising that the quartz mast tank comes with a lifetime warranty.
What’s even more amazing is…
This mast tank is the second generation model of quartz!

First of all, if you compare it from the front, there is almost no difference in appearance between hand-wound and quartz watches.
The size is also almost the same.
And since the dial and hands have been replaced, there is even less difference.

The thickness is slightly better for hand-rolled ones.
Even if I say that, I don't understand (lol)
I'm sorry.
They look almost the same from the front...

Why is it upside down? ?
The back cover is self-explanatory, and the hand-wound case is fastened with a horizontal screw.
The quartz is secured with screws in all 8 locations on the case side and back cover.
That's the only difference apart from the mechanics.

And to go back a little bit...
Quartz must-tank models have been around since the mid-1980s.
Around the 1990s, minor changes were made to the case details, movement, inner case, and crown.
This is what I researched while checking the items that arrived at my place.
It may not be completely accurate, but I think it's generally accurate.
Well, don't worry, you won't die in a different place (lol)

So I still understand why early mast tank quartz comes with a lifetime warranty.
It is possible that there is confusion,
There's no way people in that age group manage products properly, so it's quite possible.
But since it's the second generation and comes with a lifetime warranty, it shouldn't be consistent with the age...
I thought about this when I purchased the item and sent it to Cartier to try it out.
Then, surprisingly, the lifetime warranty is valid (lol)
I was really scared!

The first estimate was a normal price, so I thought, ``I guess it's no good after all.''
I checked with the person in charge.
Then, due to a mistake in the estimate, it was not covered by the lifetime warranty, so I fixed it.
The complete service is free and I picked it up today.
The complete service will continue to be free forever!
However, please note that you will need to pay for parts and battery replacement.
Battery replacement will probably be necessary and will cost around 6,000 yen.
This time we are replacing the dial and hands, so it won't be a major repair unless there is a major issue.

Anyway, this time you can choose manual winding or quartz with a lifetime warranty only for LM size.
An opportunity like this will probably never come again.
In the first place, the lifetime warranty service is a wonderful feature that cannot be found anywhere else in today's brands.
It's a good thing about Cartier, but I feel like it's also a good thing about the 1980s.
Complete service is forever free...
Once again, I am impressed by how amazing this is.

Speaking of the 80s, it was also the year I was born.
The 90s was the era in which I grew up.
I sometimes wish I was an adult at that time, but that doesn't happen.
But I like this era's music the most, so I'll choose it here.
