The Omega Speedmaster Mark III was introduced in 1971 as a successor to the popular Mark II.

One of the standout features of the Omega Speedmaster Mark III is its chronograph function. Equipped with a tachymeter scale, it allows you to measure speed.

Initial Assessment of the Watch

Examining the Overall Condition

Once you’ve acquired a Mark III or decided to restore your own, start by examining its overall condition. Look for any visible signs of wear, damage, or rust. Note any scratches, dents, or discoloration on the case. Check the crystal, dial, and hands for flaws or cracks. This initial assessment will give you a clear idea of the extent of restoration required.

Identifying the Areas of Restoration Needed

Based on your examination, make a list of areas that require restoration. This could involve polishing the case, refurbishing the dial, replacing the hands, or servicing the movement. Take note of any specialized tools or expertise you may need to acquire for specific tasks.

Determining the Feasibility of Restoration

Before proceeding with the restoration, assess whether it is economically feasible and within your skillset. Some watches may have extensive damage or require rare parts, making the restoration process costly and time-consuming. If you’re unsure about certain aspects, it’s always wise to consult with a professional watchmaker who specializes in vintage timepieces.

Disassembling and Cleaning the Watch

Gathering the Necessary Tools

Before you start disassembling the watch, gather all the necessary tools required for the restoration process. These may include a case opener, case knife, case holder, movement holder, cleaning solutions, and various sized screwdrivers. Having the right tools for the job will ensure a smooth and efficient restoration process.

Removing the Bracelet and Strap

Begin by removing the bracelet or strap from the watch. This can usually be done by using a spring bar tool to compress the spring bars and detach them from the lugs. Take care not to scratch or damage the case during this process. Once the bracelet or strap is removed, set it aside for cleaning or replacement if necessary.

Taking Apart the Case and Movement

Now it’s time to disassemble the case and movement. Use the appropriate tools to carefully unscrew the case back, remove the crystal, and take out the movement. Take note of the order in which you remove the components to ensure easy reassembly later. Place each part in a separate container or watch parts tray for cleaning and organization.

Thoroughly Cleaning the Components

Cleaning the components is a critical step in the restoration process. Use specialized cleaning solutions and ultrasonic cleaners to remove dirt, dust, and old lubricants from each part. Take extra care when cleaning delicate components, such as the dial and hands, to avoid causing any damage. Once cleaned, make sure to thoroughly dry each part before moving on to the next step.

Restoring the Case

Evaluating the Case Material

During the restoration process, carefully evaluate the case material. If it’s stainless steel, you might be able to remove scratches and dents through polishing. However, if the case is made of gold-plated material, be cautious not to strip off the plating during the restoration process. Ideally, consult with a professional watchmaker to determine the best course of action.

Removing Scratches and Dents

To remove scratches and dents from the case, start by using a suitable abrasive material, such as a polishing cloth or micro-abrasive paste. Apply gentle pressure and make controlled circular motions to buff out the imperfections. Take your time during this process, ensuring you don’t remove excess material or alter the case shape.

Polishing the Case

Once the scratches and dents are removed, you can proceed to polish the case. Use a dedicated metal polish or polishing compound to restore the shine and luster of the case. Apply the polish with a soft cloth and work in small, circular motions. Take care not to over-polish and affect the original finishes of the case.

Refinishing the Bezel and Crown

If the bezel and crown have lost their original finish or show signs of wear, consider refinishing them. This involves carefully removing the old coating or damaged material and applying a new layer of plating or coating. Again, consult with a professional to ensure the refinishing process is done correctly and matches the original aesthetics of the watch.

Resolving Issues with the Dial and Hands

Inspecting the Dial for Flaws or Damage

Inspect the dial under proper lighting for any flaws or damage. Look for discoloration, fading, or scratches on the dial surface. Pay attention to any signs of moisture damage or deterioration of the dial’s lume. Identifying these issues will guide you in determining whether the dial requires refurbishing or replacement.

Refurbishing or Replacing the Dial

Refurbishing the dial involves carefully cleaning and restoring its original appearance. This process requires delicacy, as any aggressive cleaning techniques can irreversibly damage the dial. If the dial is beyond repair, you may need to consider replacing it. Finding an authentic replacement dial can be challenging, so ensure you source it from a reputable supplier.

Repairing or Replacing the Hands

Similar to the dial, inspect the hands for any damage or deterioration. If the hands have lost their original shape or lume, you may need to repair or replace them. Hand replacement requires precision and expertise, as the hands must be aligned perfectly for accurate timekeeping. Again, consult with a professional watchmaker if you’re unsure about this aspect of the restoration.

Servicing the Movement

Understanding the Different Components

The movement is the heart of the watch and requires meticulous care during the restoration process. Take time to understand the different components that make up the movement, such as the balance wheel, escapement, gear train, and winding mechanism. This knowledge will assist you in disassembling and reassembling the movement correctly.

Disassembling the Movement

Disassembling the movement can be intricate and time-consuming. Carefully follow the manufacturer’s instructions or consult a watchmaking guide specific to the Omega Speedmaster Mark III. Take note of each step and ensure you keep the individual components organized and labeled for easy reassembly.

Cleaning and Lubricating the Parts

Once the movement is disassembled, it’s time to clean and lubricate the parts. Use specially formulated cleaning solutions and ultrasonic cleaners to remove any dirt, dried oils, or debris from the components. After cleaning, apply the appropriate lubricants to the gears and pivots, ensuring smooth operation and reduced wear.

Reassembling the Movement

Reassembling the movement is a delicate task that requires utmost precision. Refer to your documentation or watchmaking guide to ensure the correct placement and assembly of each component. Take your time during this process, as even the slightest misalignment or error can affect the movement’s functionality.

Testing and Fine-Tuning

Checking for Proper Timekeeping

Once the movement is reassembled, it’s crucial to check for proper timekeeping. Use a timegrapher or similar device to measure the accuracy of the watch. Adjust the balance wheel if necessary to achieve optimal timekeeping performance.

Checking the Functionality of Chronograph

The Omega Speedmaster Mark III is renowned for its chronograph function. After the restoration, test the chronograph mechanism to ensure all functions, including start, stop, and reset, work smoothly and accurately. Make any adjustments if required to achieve optimal functionality.

Ensuring Water Resistance

If your Mark III is designed to be water-resistant, it’s important to test its water resistance after the restoration. Consult the watch’s specifications or refer to Omega’s guidelines to determine the appropriate water resistance testing method. This step ensures the watch can withstand normal wear and tear without compromising its internal components.

Adjusting the Movement for Accuracy

Fine-tuning the movement for accuracy is the final step in the restoration process. Utilize a timegrapher or other accurate timekeeping device to make any necessary adjustments. This may involve altering the balance wheel’s timing, adjusting the regulator, or tweaking the movement’s beat rate. Achieving optimal accuracy will ensure your Mark III performs as intended.

Replacing the Crystal and Gaskets

Removing the Old Crystal and Gaskets

If the crystal is scratched, cracked, or damaged, it’s advisable to replace it during the restoration process. Carefully remove the old crystal using the appropriate crystal lift or press. Take note of any rubber gaskets or seals that need replacement, as these play a crucial role in maintaining the watch’s water resistance.

Selecting a Suitable Replacement

When selecting a new crystal, ensure it matches the original specifications and dimensions of the watch. Consult with a watchmaker or supplier who specializes in vintage Omega parts to obtain an authentic replacement. For the gaskets, choose high-quality replacements that are compatible with your Mark III’s model and year.

Installing the New Crystal and Gaskets

With the new crystal and gaskets in hand, carefully install them in the case. Use a crystal press or appropriate tool to ensure a secure fit, avoiding excessive pressure that could damage the crystal or case. Double-check the gaskets to ensure they are correctly seated and provide adequate water resistance.
