I am a 1977 Graduate of the Bulova School of Watchmaking in New York City and am a Certified Accutron Technician. I had been employed at Sirianni Bros. Jewelers for the past 24 years. I am now self-employed as a watchmaker doing work for other jewelry stores in Pennsylvania, Ohio and New York. I also do repairs for individual customers and collectors.
I provide top quality watch repair at a very reasonable price with a quick turnaround time. I am very experienced with vintage pocket watches and evaluating those watches that can be affordably repaired.
Please call or email with details of what type of watch you have before you ship.
I am always available by telephone or e-mail to answer questions about your next watch repair project.
I am a member of the Pennsylvania Jewelers Association.
I am a member of the National Association of Watch and Clock Collectors.
There is no need to bid on my Ebay auctions to have your watch repaired. Please send the watch directly to me. This will save me from reposting the auction and allow me to keep my prices down.

In addition to their exterior beauty, watches are also an incredible feat of engineering and craftsmanship. Many complicated parts must all work in tandem in order to not only tell time, but perform the other functions that many of todays watches perform.
Watches contain many parts that work together to tell time, as well as perform other useful functions. These could include a chronograph, altimeter, alarm, day/date calendar, phases of the moon, slide-rule, etc. Here are descriptions of the major internal and external parts and their functions.
The cover over the watch face is called the crystal. There are three types of crystals commonly found in watches: Acrylic crystal is an inexpensive plastic that allows shallow scratches to be buffed out. Mineral crystal is composed of several elements that are heat-treated to create an unusual hardness that aids in resisting scratches. Sapphire crystal is the most expensive and durable, approximately three times harder than mineral crystals and 20 times harder than acrylic crystals. A non-reflective coating on some sport styles prevents glare.
A watch's hands are the pointing device attached at the center and circling around the dial indicating hours, minutes, seconds and any other special features of the watch. There are many different types of hands: Alpha: A hand that is slightly tapered Baton: A narrow hand sometimes referred to as a ‘stick hand’ Dauphine: A wide, tapered hand with a facet at the center running the length of the hand Skeleton: Cutout hands showing only the frame Luminous: Hand made of skeleton form with the opening filled with a luminous material
The surface ring on a watch that surrounds and holds the crystal in place is called the bezel. A rotating ratchet bezel moves in some sport watches as part of the timing device. If rotating bezels are bi-directional (able to move clockwise or counter clockwise), they can assist in calculations for elapsed times.
The knob extending from the watchcase that is used to set the time, date, etc. is called the crown. Most pull out to set the time. Many water-resistant watches have crowns that screw down for a better water-tight seal. Most water resistant crowns contain a gasket inside the crown to help maintain water resistence.
The watch face that contains the numerals or surface design is called the dial. While these parts are usually applied, some may be printed on. Sub-dials are smaller dials set into the main face of the watch. These can be used for added functions, such as elapsed times and dates.
The watchcase is the metal housing that contains the internal parts of a watch. Stainless steel is the most typical metal used, but titanium, gold, silver and platinum are also used. Less expensive watches are usually made of brass that has been plated with gold or silver.
A bracelet is the flexible metal band consisting of assembled links, usually in the same style as the watch case. Detachable links are used to change the length of the bracelet. Bracelets can be made of stainless steel, sterling silver, gold, or a combination.
A strap is simply a watchband made of leather, plastic or fabric.
A watch’s main timekeeping mechanism is called its movement. Today’s watch movements fall into two categories: Automatic mechanical or quartz. Automatic mechanical movements mark the passage of time by a series of gear mechanisms. Most automatic movements are wound by the normal, everyday movement of your wrist, which charges the watch’s winding reserve. Quartz movements are powered by a battery and do not stop working once removed from your wrist.
The mainspring is the energy source responsible for powering the watch movement (as opposed to a battery in a watch with a quartz crystal movement). The spring is wound, either manually (using the winding stem) or automatically, by the motion of the wearer’s wrist. Potential energy is stored in the coiled spring, then released to the gear train which transmits the power to the escapement and motion work, which turns the hands on the watch dial.
The regulating organ of a watch with a mechanical movement that vibrates on a spiral hairspring is called the balance wheel. Lengthening or shortening the balance spring makes the balance wheel go faster or slower to advance or retard the watch. The travel of the balance wheel from one extreme to the other and back again is called oscillation.
This series of small gears in both quartz and mechanical movement watches is responsible for transmitting the power from the battery (in a quartz watch) or spring (in a mechanical watch) to the escapement, which distributes the impulses that mark the time.
This part of the watch restricts the electrical or mechanical impulses of the gear train, metering out the passage of time into equal, regular parts.
The motion work is a series of parts inside a watch that receive power from the escapement and gear train, which distribute and generate the watch’s power. The motion work is responsible for actually turning the watch’s hands.
