The wristwatch was not an automatic watch, but appeared to be a manual-winding type.
It was a simple watch with black letters on a white dial without any extra decoration, and appeared to Jin to be of a rather old design.
The second hand was not coaxial with the minute and hour hands, but was mounted on the lower center of the dial, between the center and 6 o'clock.
The manufacturer was S. It is a major watch manufacturer that Jin is familiar with.
The glass was cracked, suggesting that the watch had been bumped or dropped.
"I don't know what it was used for, but it is a very fine piece of work, and I heard that it was a favorite item of a wise man (Mags). It is an heirloom in my family."
Fadon's words brought Jin back to himself.
"This is ......."
"Jin, do you know what it is?"
Even Goose did not seem to know what this was.
"It's a ...... watch."
"A watch? ......It is ...... if you ask me, but a watch? With this?"
Jin explains simply.
"Yes. It's a small watch that you wear on your arm like a bracelet.
"If it's ......, what do these hands represent?"
Goose pointed to the second hand.
"Let's go in order. This short hand is the short hand or the hour hand, which indicates the time. And the long hand is the long hand or the minute hand, which represents the minutes.
In sundials and moonset clocks, the shadow acting as a hand makes a round in a day, but in this wristwatch, the hour hand makes a round in half a day.
It is not surprising that no one thought of the watch as a clock itself, even if they thought it was similar.
"So, this time clock? So, is this clock ticking in two-hour increments?"
So the question comes up.
"No, this clock goes around once in 12 hours.
When Hitoshi said this, Goose shouted, as if he understood.
"Oh, I see. We say 8 a.m. and 8 p.m. too. So for every morning and afternoon, this goes around once. Surely you can't tell 8:00 in the morning from 8:00 at night."
"That's what I meant. That's what I'm talking about, Goose.
Jin praised Goose's comprehension and resumed his explanation.
"So, this long hand or minute hand goes around once in an hour.
"How?
"How?"
Goose and Fadon looked at each other in disbelief that the hands, which seemed to be coming out of the same place, were turning at different speeds.
"It's the same thing, but there's a different wheel, and it's changing the speed of rotation, right?"
"Yes, that's right."
Jin was surprised to hear Hannah's words of explanation.
"So, this little hand is the second hand."
"What? Can it measure seconds?
It is true that in a world that uses sundials and moon clocks, there are units of measurement such as hours, minutes, and seconds, but there are few opportunities to actually measure them.
No wonder Goose was surprised.
"......What are you going to do with such detailed measurements of time?"
A natural question from Fadon. He knew the second as a unit of time, but had never had a chance to use it.
"Let's see, ......."
Jin tried to come up with an easy-to-understand analogy.
"Do you know the relationship between distance, speed, and time required?"
"If you multiply the speed by the time, you can find the distance traveled, right?"
Now Goose. Mayor Fadon was nodding his head next to Goose, so it seems that he understands.
"So, if we divide the distance by the time, we can find the speed, right?
To this he replied, "Of course.
"If we know the distance, we can determine the speed by measuring the time required with a clock, right?
In this case, the speed is the average speed.
"Ah, I see, so the concept of is there to make such measurements and calculations in more detail!"
Goose said, smacking his hands together in amazement.
"That's what I meant. But you should know that you will need it in more situations than just that."
Everyone else listened to Jin's explanation and tried to digest it in their own minds.
Erza and Saki were no exception. There are clocks in Horai Island, but they are not this small and precise.
This means that Jin and those who are connected to him cannot make something like this. At least, not yet.
"Nido-den."
The mayor, Fadon, spoke to Jin in a reverent manner.
"You are the one who recognized at a glance that this relic is a , are you related to the ?
Jin thought about this question for a moment before replying.
"I am sure that they are related to each other, but I don't know him directly. I am sure that they are from the same hometown, but I have no direct acquaintance with them.
"I suppose that's true."
It would be extraordinary if he had known the sage Magus a thousand years ago.
Fadon nodded in agreement.
"This is ...... Faso, I came here to learn more about Mags.
"I see... If you say that we could be from the same country, it is only natural..."
As Fadon, I understand the feeling, he said.
"So you have a clue about the wise man (Mags) ......."
Then he kindly asked me if I had any information about Mags.
"......I think it would be better to go further north from here, to ."
Fadon told us that Dachte was the capital of Huso.
"There are some ancient documents said to have belonged to a wise man (Magus), and there is a possibility that some relics are kept there.
This was good news. It was much more efficient than going around the town in the dark.
"Thank you very much."
Jin thanked him. He had found another clue.
"But you're from the same town as Mags, ......?"
"Are you curious?"
Fadon muttered, and Jin asked back,
"Yes, well, I'd be lying if I said I wasn't concerned about it, but it's not like it would make any difference to me.
He replied, "Well, I'd be lying if I said I wasn't concerned about it, but it doesn't really matter what I know.
He may be saying that he appreciates the achievements of Magus, a wise man who lived more than 1,000 years ago, but his birthplace does not matter much.
It is a little difficult for Jin to understand, but he accepts that there is such a way of thinking.
"By the way, can you fix this ?"
Hwadong asked, looking at Jin's face. Jin thought for a moment before replying.
"I think it can be fixed, but it will be difficult. It would take a long time.
Jin himself had never disassembled and repaired a watch before. And with a wristwatch, it would be impossible to repair it without special tools.
The only possibility would be to have a <> do it.
However, Jin was also interested in the construction and reproduction of the watch.
"If you lend me the watch for a day, I'll be able to make some kind of decision. ......"
"Hmm. ......."
Fadon thought for a moment and nodded.
"Okay, that's fine. I trust you, Nidou-dono, and I will lend it to you.
"Thank you very much."
Jin thanked him and accepted the box containing the watch.
After Hwadong and the others left the room, Goose reminded him.
The mayor trusted Jin and entrusted the watch to me, so please fix it somehow!
"I know."
Jin replied and took the watch to his room. He gently places the box on the table.
At the same time, he called out to Reiko and asked her to contact the old man.
"Contact him to forward five miniature craftsmen (smiths)".
"Yes, father."
Reiko contacts the old man with the built-in manacam.
A mini-craftsman (Smith) appears in about a minute. Jin orders him to disassemble, analyze, and repair the watch.
