Doing electrical tests on Swiss made chronograph watches using Le Arsi Quartz Watch Analyzer!
The electrical tests for quartz watches mentioned in international technical manuals can be performed by the first Filipino-made tester, created by Le Arsi—your instructor for the Watch Repairing Course at PWRTCI MANILA.
​The Le Arsi Quartz Watch Analyzer features adjustable voltage used for various testing procedures on electronic watches, such as the Swiss-made ETA 251.262 chronograph.
​Here is how to test this chronograph watch:
​Power On & Voltage Setup: First, turn on the power switch located at the back of the tester. Adjust the voltage to 1.5V and flip down the toggle switch in the center.
​Probe Check: Touch the tips of the two probes together—if it beeps and the LEDs light up, the probes are powered at 1.5V.
​Connection: Insert the black probe into the (-) tongue of the battery compartment and the red probe onto the (+) plate or bridge of the movement.
​Initial Observation: You will hear multiple pulses, and looking at the mirror underneath, you will see the hands suddenly rotate. The small seconds hand in the sub-dial at the 6 o'clock position runs in sync with the LED pulse and the tester's sound. However, the center seconds chronograph hand does not move.
​Testing the Chronograph: Holding the two probes steady with one hand while the basic seconds hand continues running, press the chronograph start push button. The center seconds chronograph hand still does not move, even though the LEDs signal that two mechanisms are firing (corresponding to basic time and the chronograph).
​Final Diagnosis: There is a restriction in the chronograph mechanism; it may be dirty and requires cleaning or a full service.
​Most students who studied at PWRTCI own a tester like this, making it easy for them to understand the electrical tests performed even in other countries.

WALANG PASOK PA RIN NGAYONG LUNES SA PWRTCI DAHIL SA MASAMANG PANAHON. MAG-INGAT ANG LAHAT.

My family gathered for a simple celebration on my 70th birthday—a life filled with challenges, the strengthening of hope and faith, the fulfillment of everyone’s responsibilities, and the gift of a renewed, meaningful life over the past three years and for the years ahead. Praise God for the hardest trial I faced and overcame on August 7, 2023—which was also my birthday—when I was bedridden in the hospital following an angioplasty procedure where two heart stents were placed at the Philippine Heart Center. Ito Ang Sambahayang Iglesia Ni Cristo. Praise the Father, the owner of our lives!

The Filipino Horologist

If you don’t catch Le Arsi crafting tiny wristwatches, he’s almost certainly building giant tower clocks across the Philippines.
​Take this 2-meter-wide clock, for example, which Le Arsi and his team at Big Tic Clockmaker installed in 2016 on a newly constructed building along Kennon Road in Baguio City. Photos from the installation show a team made up of Choir Member, PD, Katuwang saTribuna and fellow brethren from the Iglesia ni Cristo (INC).
​The clock’s internal mechanism—or movement—is an original design by Le Arsi himself, making it a first in the Philippines and potentially the world. He dubbed it the "two-wheel direct drive," meaning it relies on only two wheels inside the mechanism. Despite its simple design, it achieves an impressive accuracy of +2 to +5 minutes per year.
​Big Tic Clockmaker specializes in manufacturing large-scale clocks throughout the Philippines for tourist spots, commercial buildings, rotundas, riverside cafes, shopping malls, golf courses, building lobbies, churches, transport terminals, and more.
​Israel "Le Arsi" Angeles is not only an instructor for the vocational watch repairing course at PWRTCI, but he is also an innovator. His Filipino-made "two-wheel direct drive" clock comes with numerous advantages: it is easy to produce, has very few moving parts subject to friction, boasts a long operational lifespan, and offers several other key benefits.

Israel "Le Arsi" Angeles is a master watchmaker, inventor, and vocational instructor in watch repair in the Philippines.

The broad vision and deep insight of Le Arsi, your instructor in the watch repairing course at PWRTCI in Manila, reflect an extensive mastery of the theoretical and practical aspects of horology. His expertise spans from the intricate fabrication of rare and hard-to-find components for luxury timepieces to the complete engineering of custom clock movements—movements that are now utilized in major large-scale clock installations across the country.
​ Prominent examples include the famous Luneta Flower Clock and the Masonic Clock along Roxas Boulevard. Le Arsi has maintained a continuous monthly government maintenance contract for these iconic landmarks from their installation in 2011 through to 2026. Built on his proprietary mechanism design, this same system powers numerous other tower clock installations throughout the Philippines.
​ It is no wonder that whenever a student faces a complex issue with a movement, watching Le Arsi demonstrate the precise solution leaves them applauding with genuine excitement for what they’ve learned.

The Philippine Watch Repair Training Center, Inc. Manila

Many of those who enrolled here at PWRTCI actually started out having someone else repair watches for them because they didn't know anything about timepieces yet.
​As it happened, they grew fond of buying and selling watches. Whenever they sold a watch that eventually stopped working, they relied on their designated watchmaker to fix it. However, a huge number of customers kept coming back with the exact same complaint—the watches were still stopping intermittently.
​Frustrated by these constant issues, they decided to enroll at PWRTCI. It was here that they discovered the root causes behind their former repairer's endless "back jobs" (recurring repair issues).
​ Now, the tables have turned: their former repairer is the one coming to them for advice and guidance on how to resolve various watch problems. This July 2026 Enrollment is open at PWRTCI!
