BIG TIC CLOCKMAKER INSTALLATION!

From the moment of touchdown after a 12-hour journey to the final installation of the 1.2-meter clock on the church facade, it is a wonderful feeling to see that clock finally running.
​The movement of this clock is an original design by Le Arsi a Filipino watch and clockmaker since 1973 who is also an instructor for the watch repairing course at PWRTCI Manila, where he teaches those aspiring to become watch technicians. He has named this design the "two-wheel direct drive," the first of its kind in the Philippines.

Le Arsi is traveling to the province today with the Big Tic Clockmaker team to install a large clock commissioned for a church building. The clock’s movement features a custom design by Le Arsi called the "two-wheel direct drive." This marks a milestone as the first of its kind featuring both Filipino craftsmanship and Filipino innovation.
​As an instructor at the Philippine Watch Repair Training Center, Inc. (PWRTCI) in Manila, Le Arsi actively accepts students eager to learn the craft of watch servicing and repair. His journey in horology began in 1973 and continues to this day in 2026. Since the 1990s, he has mentored countless individuals, many of whom have gone on to establish their own service centers across the country.

While dealing with the intricate tasks involved in small watches, it is impossible to ignore the requests of those who dream of having giant clocks on their buildings. Thus, when you don't see Le Arsi working on small timepieces, you will surely find him crafting massive clocks using his own proprietary clock movement design called the "2-wheel direct drive"—a first of its kind in the Philippines, created by the instructor of the watch repairing course at the Philippine Watch Repair Training Center in Manila. This clock sized 1.2 meters is bound to the southern part of the country this April.

Following the previous post, you can see that the broken pivot stuck in the cannon pinion has been removed. Currently, the new pivot is in the process of being thinned down to the correct size. Now the movement is perfectly running with a new center post.

PROBLEM: A broken center post is stuck inside a closed cannon pinion. It is a massive headache for the watchmaker to resolve because there are no replacement parts available for this rare, high-end watch!

The tallest clock in the Philippines is the MDC 100, located along C5 Libis, Quezon City. It was created and installed by Le Arsi and his team in 2012.
​The clock measures 6.5 meters wide and is situated on the 33rd floor of the building. It utilizes a clock movement designed by Le Arsi himself, which he calls the "two-wheel direct drive." Le Arsi is an instructor for the watch repairing course at PWRTCI Manila, where he passes on his skill and expertise in watch repair to those who wish to learn.

Handcrafted Precision: How a Filipino Master Overcame Global Parts Shortages
​In the world of luxury horology, "parts availability" is often the greatest hurdle for independent watchmakers. When a high-end timepiece required a new sweep second pinion pivot that couldn't be sourced locally or internationally, Le Arsi—a veteran with 53 years in the trade—chose to manufacture the component himself.
​Le Arsi, a lead instructor at the Philippine Watch Repair and Technical Center, Inc. (PWRTCI) in Manila, demonstrated that old-school craftsmanship still holds its own against modern manufacturing. To prove the viability of the handcrafted part, the watch was placed on a highly sophisticated timing machine. The result? A perfect "OK" reading, signifying that the geometry and friction of the handmade pivot met the rigorous standards of the movement.
​This achievement serves as a testament to the high level of technical education provided at PWRTCI and the enduring expertise of Filipino watchmakers.

Don’t let your tools become a liability!
​In the last two months, we've seen two separate cases where watchmakers accidentally broke the sweep second pinion of a Patek Philippe while using a Timegrapher microphone holder. It’s a heart-stopping mistake, but a vital lesson in handling high-end movements.
​Thankfully, under the expert guidance of our instructor, Le Arsi, we successfully crafted and replaced the broken pivots. Precision restored!

Le Arsi’s Electronic Watch Analyzer
​Here is an electronic watch analyzer—handcrafted by Le Arsi—featuring both an audible alarm and an LED indicator. After cleaning and lubricating the 2141 movement, he tested it using his device’s adjustable power supply.
​After setting the output to 1.36V, he connected the black probe to the movement’s ground plate and the red probe to the positive terminal inside the battery compartment. The LED lit up immediately, accompanied by a continuous high-pitched tone from the tester. Upon closer inspection, you can see in the mirror that the seconds hand is not moving.
​He then gave the watch case a light tap; suddenly, the LED turned off and the tone dropped to a lower pitch. This signal from the tester indicates that the movement is now running, and the change in sound and light confirms that the Accutron 2141 is reaching its normal current consumption.
​Innovation in Focus
​The concept of a tester that uses sound to measure current consumption is an original idea by Le Arsi. It was designed so that a watchmaker can use their ears to monitor the movement's status while keeping their eyes fully focused on the delicate and sensitive electronic parts of the watch. This is a first of its kind in the Philippines, created specifically for Le Arsi’s students at PWRTCI

The electronic tuning fork watch played a pivotal role in the emergence of quartz watches. When the Accutron debuted in the 1960s, it brought a massive shift in timekeeping accuracy, far surpassing traditional mechanical watches. This innovation paved the way for the quartz watches of the 1970s, which utilized a quartz oscillator shaped similarly to a tuning fork as their time base.
​Currently, Le Arsi is repairing a Bulova Accutron 2141, which originally requires a 1.35V Mercury battery. Unfortunately, 1.35V mercury batteries are no longer available because they have been banned from public sale.
​To solve this, Le Arsi is looking for a way to reduce the voltage of a modern 1.5V battery to match the Accutron's requirements and maintain its accuracy. He is choosing between two methods to ensure the tuning fork's vibrations remain precise: installing a diode or using a resistor.
Le Arsi first decided to try using a resistor to drop the voltage from 1.5V to 1.35V. As seen in the picture, he created a custom contact pad (right) and placed a resistor chip inside it. The battery he is using for this setup is a 920 (Silver Oxide). Stay tuned for the results!
