Narrator:
The first aluminum boat
Was launched as a simple skiff

In the middle
Of the last century.

Fishermen loved
The lightweight hull

Because it could be pulled in
And out of the water more easily

Than the wooden boats
Of the day.

Decades later, aluminum boats
Have gone high-end,

But they still have
That lightweight appeal.

Since aluminum hulls aren't
As heavy as other types,

These boats will go farther
On a tank of gas.

They make them
From high-grade aluminum

That's corrosion-resistant.

Rollers flatten the metal,

And a blade called a slitter
Cuts it to length.

A computer-guided router
Then makes precise cuts

To produce parts that
Will fit together perfectly,

Like this bracket
To reinforce the stern.

They cut the boat's
Larger components

With a computerized
Plasma torch.

It can cut a wider path
Than the router.

They transfer the cut parts
To a pallet.

This is the boat's bottom panel.

A long piece of aluminum
Will be the gunnel,

Which is the upper edge
Of the hull.

They bend it
Around a wooden template

To give it
The correct curvature.

Next, they reinforce the bow
With an extra plate of aluminum

To withstand pounding waves.

They brace the other end
With numerous stiffeners

And screw them into place.

The screws act
As a clamping system,

Until the parts of the boat
Can be permanently attached.

A line of caulking
Helps waterproof the seam

Between the hull
And the back of the boat,

Called the transom.

Again,
Screws hold everything together,

As the painstaking clamping
Continues.

They join the two sides
Of the bow

And hold the ends together
With a vise grip.

This strip of aluminum will act
As the spine of the bow.

It's called the brace plate.

More screws tack it
Into position.

They attach the sides
To the rest of the hull.

Now they drill hundreds of holes
Along the seams

And plug them with rivets.

They extract the clamping screws

And fill their holes
With more rivets.

They install the gunnels
On the rim of the hull.

And now it's time
For the tank test.

They lower the boat into a tank
To confirm that it's watertight.

If they find any leaks
In all those rivets,

They'll make
The necessary adjustments.

They spray foam
Into the bottoms and sides

To keep this boat afloat

In the event
That something punctures it.

And then they rough up
The surface

To allow paint to better adhere.

They move to the interior

And install felt
On the storage panels

To give them
A more finished look.

Then they lay the carpeting
Port to starboard.

Next comes
The plastic fuel tank.

All they have to do
Is connect the fuel-line hoses

And secure them
With a stainless steel collar.

The dash panel fits
Onto the front.

It's pre-wired,

So they simply connect it to
The boat's main wiring harness.

Next, they apply lubricant
To the motor's propeller shaft.

This allows the propeller
To slide on easily.

They tighten it
With a pneumatic ratchet.

Then they hoist the motor
Onto the stern

And bolt it into position.

With the luxurious interior
Now complete,

This metal boat bears
Very little resemblance

To its utilitarian predecessors.

This particular model
Doubles as a fishing boat

And a pleasure craft.

And it proves
That aluminum boats

Are no longer just
A basic form of transportation.

Narrator: the alpine horn
Dates back some 2,000 years

To the celtic tribes

That inhabited
The northern slopes of the alps.

Traditionally,
Mountain dwellers blew the horn

To announced daily activities,

Such as round-up time
For livestock.

As modern communications
Reached those altitudes,

The horn's role
Became strictly musical.

[ alpine horn playing ]

An alpine horn's sound
Travels about 5 miles,

Thanks to the instrument's
Length and shape.

Following
A centuries-old tradition,

The horn maker harvests spruce

At a specific time
In the lunar calendar,

When tree wood
Is supposedly most resonant.

Once the spruce logs dry out,
Which takes at least nine years,

He saws them into planks.

Then he traces
And cuts out the shape

Of the horn's curved bell
Twice --

Once for each half.

He measures and marks
How much wood he must hollow out

With his drill press.

It's tricky
Because from top to bottom,

The bell's inside cavity

Progressively widens
And deepens.

Next, he runs glue

Along the perimeter
Of both bell halves,

Then joins them with a sheet
Of newspaper in between

To prevent a permanent bond.

He'll have to
Pry them apart later

To finalize their shape.

Once dry, he tears off
Excess newspaper,

Traces the circumference of the
Bell's top and bottom openings,

Then measures
And draws the bell's shape

Between those two openings.

Once again,
Following the lines he drew,

He cuts out the shape.

To check his work, he uses
A series of sizing templates.

He lines them with charcoal,

Then slips the first template
Onto its designated position

At the top of the bell.

The charcoal marks any wood

That he still needs
To shave off.

He repeats this procedure
With each template,

Working his way down
Until the bell is rounded

To the proper
External dimensions.

Now for the bell's
Internal dimensions.

The horn maker detaches
The halves.

He scores a line running
The length of the bell half

On each side.

This marks
The inner-wall thickness

He's going to create.

Using a grinder
With a rough grit abrasive,

He wears away the wood
Right up to the score lines.

The holes he made earlier
Tell him how deep to grind.

Then he switches
To a finer grit abrasive

To grind the walls down
Another millimeter.

He checks his work
With a measuring gauge,

Then glues the halves together
Again, this time permanently.

The horn maker constructs
The bell's other section

In halves, as well,
Rounding them off on a lathe.

He coats them in glue
And wraps them in rattan.

The rattan solidifies
The structure somewhat

But is primarily for decoration.

Once the glue dries,

He'll glue aluminum connecting
Dowels to each section.

These will enable the musician

To assemble and disassemble
The horn parts.

The bell is truly
The alpine horn's showpiece.

Horn makers
Typically embellish it

With painted scenes or motifs.

This horn will boast
A colorful bouquet

Of traditional swiss flowers.

Fully assembled,

An alpine horn is between
10 and 13 feet long --

The length determining
The pitch of the instrument.

Musicians use lip movements

To modulate the vibration
Of the air column inside.

Different vibrations
Produce different notes.

Narrator: throughout
Most of the 19th century,

The wristwatch was a piece
Of jewelry worn by women.

Men carried pocket watches.

It was during the boer war
In 1899

That british soldiers decided
Fumbling around

For a pocket watch during battle
Was a serious waste of time.

The tools of the trade
Haven't changed much

Since pocket watches
Ruled the day.

In this swiss workshop,

The mechanisms
Are meticulously handcrafted,

Just like they were
Centuries ago.

The watchmaker starts

By polishing parts
To a mirror finish.

He mixes his lavender and almond
Oils with a diamond paste.

He extracts a part
Called the cage

From its storage solution,

Sets it in the paste,

And polishes it
Against a zinc block.

He brushes the dust off the cage
With a soft piece of wood.

Another watchmaker
Polishes its edges,

Removing tiny bits of material
So other parts can fit to it.

The technician attaches gears
To the cage.

These gears are the balance
And escape wheels.

He fixes the gears
On tiny rubies

Because they don't
Wear down easily.

The second half of the cage
Completes this mechanism,

Called the tourbillion.

Invented in 1789,
These rotating gears in a cage

Counteract the effect of gravity
On timekeeping

For more accurate results.

The watchmaker
Now magnifies the assembly

And projects the image
Onto a screen

To confirm
That the gears and levers

Are interacting correctly.

Next, he secures
A wound-up spring in a barrel.

This is the main spring that
Powers the gears of the watch.

He dips a pin in some grease

And uses it to lubricate
The spring.

Then he caps the mainspring
With a cover

And tamps it down
With a special tool.

He carefully positions
The barrel in its slot

On the main plate.

The watchmaker now installs
Another series of gears

On the main plate.

They'll transfer power

From the spring
To the tourbillion.

He attaches the bridge
To the gears

To act as a pivot as they turn.

Another spot of grease

Keeps these wheels
Turning efficiently.

With the spring barrel

And its transmission gears
Assembled,

Production now reaches
A critical moment.

He places the mechanism
In a holder

That makes it easier
To install the tourbillion.

It's a tricky job.

The cage must be
Precisely positioned

For its gears to receive power
From the spring.

He now transfers the mechanism
To another holder

To insert the winding stem.

Next, he engraves the circular
Pattern onto a bridge plate.

This high-end finish
Is called perlage.

The technician attaches
The textured bridge

To the dial side of the watch.

He assembles more gears

And a numbered wheel
To the bridge.

These gears will provide
The date information

For this timepiece.

Another bridge secures the gears
That lead to the date wheel.

He fastens it with tiny screws.

He slides the second date wheel
Onto its axle

And checks
The setting mechanism.

We'll have
The up-to-the-minute details

As this watch
Gets a beautiful face.

Narrator:
Even in the age of digital
And electronic wristwatches,

The mechanical watch has
An appeal that's timeless.

Some are among
The most complex in the world

And can cost
In the six-figure range.

At that price,
Time is truly a luxury.

In a factory nestled
In the scenic swiss countryside,

A highly-skilled team has
Assembled the inner workings

Of a luxurious
Tourbillion wristwatch.

Now a watchmaker fits
The handcrafted face

Onto the mechanisms.

Using a special tool,

He presses the hands onto an
Axle at the center of the watch.

This enables him
To set the time and date.

The watch will be encased
With 18-karat red-gold bezels

Sealed against the elements
With rubber rings.

He now fastens the middle casing
To the mechanism,

Then completes the installation
Of the winding stem and crown.

The watchmaker
Lubricates the bridge

For the auto-winding system,

Then engraves a parallel-ribbed
Pattern onto it.

This adds visual interest
To the bridge,

Making this luxury watch
Look good inside and out.

After the bridge
Has been set with jewels,

It's ready to be installed
At the center of the watch,

Where its jewels will keep parts
From rubbing against each other,

Causing wear and tear.

An artist now engraves the rotor

That's to be attached
To the bridge.

It's this part that will
Automatically wind the watch.

It's a signature piece

That can reflect
The customer's individual taste.

This stylish-looking rotor

Is now ready to be secured
To the bridge.

Once installed,

Even the slightest movement will
Cause this rotor to oscillate,

And that action winds up
The mainspring of the watch.

The watchmaker now shields
This timepiece with a glass dome

And then vacuums dust
From the next gold bezel.

He carefully cleans
This clear sapphire window

Because even the tiniest speck
Of dirt

Could cause the watch to fail.

He snaps the front bezel
Onto the watch,

Then, using a special device,

He presses the bezel
To secure it.

This action also squeezes
The rubber ring

Between the bezel and the watch

To create waterproof seal.

This watch will now
Be water-resistant

To a depth of nearly 330 feet.

The back casing
Screws into place

So it can be removed
For maintenance work

During the life of the watch.

Using a special tool,

He tightens the casing
To just the right tension.

He then inspects the watch

To confirm that the rotor moves
Freely within the case.

Next up is a computer analysis
Of the mechanism.

A device holds the watch
And simulates wrist movements,

While the computer evaluates
Its accuracy.

[ pinging ]

That's the sound
Of a minute repeater,

Which is a feature
On some models.

When triggered,
It chimes the time.

And now this watch
Takes the plunge

Into a container of water.

If bubbles appear,
It would signify a leak.

But there are none,
So this watch is waterproof.

This incredible watch
Will set you back $150,000.

But it will be an heirloom piece
That stands the test of time.
