The Omega Seamaster Diver 300M is one of Omega's most recognizable diving watches, admired for its exceptional water resistance, robust construction, and reliable Co-Axial automatic movement. While designed for demanding environments, regular maintenance remains essential to preserve its long-term performance.

This service case highlights how a complete overhaul successfully restored a Seamaster that had developed moisture-related issues.

Customer Complaint

The customer reported that the watch had accidentally been exposed to water during a swimming trip several weeks earlier.

Soon after, the following symptoms appeared:

• Light condensation inside the crystal

• Daily timekeeping became inconsistent

• Reduced power reserve

• The seconds hand occasionally hesitated

• Manual winding no longer felt smooth

To avoid permanent movement damage, the customer immediately brought the watch in for inspection.

Professional Diagnosis

After opening the case, our watchmaker discovered traces of moisture inside the movement.

Further inspection revealed:

• Moisture contamination on several movement components

• Degraded lubricants caused by water exposure

• Minor oxidation beginning on selected steel parts

• A worn case-back gasket that no longer sealed properly

• Dust particles inside the automatic winding mechanism

Fortunately, the movement had not suffered severe corrosion, allowing it to be fully restored.

Complete Service Process

The repair included the following procedures:

• Complete movement disassembly

• Ultrasonic cleaning of all movement parts

• Removal of moisture residue and oxidation

• Inspection of the escapement and gear train

• Replacement of all waterproof gaskets

• Fresh application of Swiss-grade lubricants

• Movement reassembly and regulation

• Water-resistance pressure testing

• Multi-day accuracy and power reserve testing

Each component was carefully inspected before reassembly to ensure reliable long-term operation.

Final Results

Following the complete overhaul, the watch achieved excellent performance:

• Stable daily accuracy within professional standards

• Full power reserve restored

• Smooth manual and automatic winding

• Crystal completely free of condensation

• Water-resistance successfully passed pressure testing

The customer was pleased that the watch had been restored before moisture caused permanent damage.

Preventing Moisture Damage

Even professional diving watches require periodic inspection to maintain their water resistance.

Owners are encouraged to:

• Replace waterproof gaskets during scheduled servicing

• Have water resistance tested once a year

• Avoid operating the crown or pushers underwater

• Rinse the watch with fresh water after swimming in salt water

• Schedule a complete movement service every 3–5 years

Regular maintenance helps protect both the movement and the long-term value of your luxury timepiece.

The Rolex Explorer II has long been recognized as one of Rolex's most reliable professional tool watches. Designed for explorers, mountaineers, and frequent travelers, it combines exceptional durability with the precision of the in-house Calibre 3285 automatic movement.

Like all mechanical watches, however, even a Rolex requires regular servicing. Without proper maintenance, lubricants gradually deteriorate, increasing friction inside the movement and affecting long-term performance.

Customer Complaint

The owner had worn this Explorer II almost every day for over eight years without a complete movement service.

Recently, several issues began to appear:

• Daily time loss of approximately 35 seconds

• Reduced power reserve

• Manual winding felt noticeably heavier

• Slight resistance when adjusting the GMT hand

• Rotor noise became more obvious during normal wear

Concerned about possible movement damage, the customer brought the watch in for a comprehensive inspection.

Professional Inspection

The watch was first tested on a professional timing machine, where the movement showed low amplitude and inconsistent accuracy.

After complete disassembly, our watchmaker identified the following conditions:

• Lubricants had significantly dried out

• Dust and residue had accumulated inside the automatic winding system

• Increased friction on several gear trains

• Aging waterproof gaskets

• Minor wear on the winding components caused by insufficient lubrication

Fortunately, no major movement parts required replacement.

Complete Service Procedure

To restore the watch to optimal condition, a full overhaul was carried out, including:

• Complete movement disassembly

• Ultrasonic cleaning of every movement component

• Inspection of the gear train, escapement, and winding system

• Replacement of all waterproof gaskets

• Application of fresh Swiss-grade lubricants

• Precise movement reassembly

• Timing regulation and calibration

• Waterproof pressure testing

• Multi-day accuracy and power reserve testing

Each step was completed according to professional Swiss watch servicing standards.

Final Performance Results

After servicing, the Explorer II demonstrated excellent performance:

• Daily accuracy improved to approximately +2 seconds

• Stable movement amplitude

• Smooth manual winding

• Efficient automatic winding performance

• GMT hand adjusted smoothly

• Waterproof performance passed pressure testing

The customer commented that the watch performed almost like new after the overhaul.

Why Regular Maintenance Is Important

Luxury mechanical watches contain hundreds of precision-engineered components working together continuously. Over time, lubricants naturally degrade, even if the watch appears to function normally.

Professional servicing every 3 to 5 years helps:

• Maintain timekeeping accuracy

• Reduce internal wear

• Preserve waterproof performance

• Extend the lifespan of the movement

• Prevent costly future repairs

Routine maintenance is one of the best ways to protect the long-term value and reliability of a fine mechanical timepiece.

The Audemars Piguet Royal Oak is one of the most influential luxury sports watches in modern watchmaking history. With its distinctive octagonal bezel, integrated bracelet, and exceptional craftsmanship, the Royal Oak changed the perception of what a luxury watch could be.

Today, it remains one of the most iconic collections from Audemars Piguet, admired by collectors around the world for its unique design and rich heritage.

The Birth of the Royal Oak

• Limited edition collector pieces

Each generation continues the original design philosophy while introducing advanced mechanical innovations.

• Automatic winding systems

• Hand-finished bridges and components

• Precise mechanical regulation

• High-quality decoration

• Complex functions in advanced models

The combination of technical performance and artistic finishing represents the true spirit of Swiss haute horlogerie.

Maintenance and Servicing of a Royal Oak

Due to its sophisticated construction and high-precision movement, regular maintenance is essential for keeping a Royal Oak in excellent condition.

Professional servicing usually includes:

• Accuracy adjustment

• Water resistance testing

• Exterior polishing when required

Regular maintenance helps reduce mechanical wear and preserves the performance and value of the watch.

Its groundbreaking design, exceptional craftsmanship, and historical importance have made it a symbol of innovation and creativity in Swiss watchmaking.

The Royal Oak is not only a timepiece but also a milestone that changed the future direction of luxury sports watches.
