Three Levels of Care — One Consistent Standard

Each tier is designed for a specific kind of need. The method and documentation are the same regardless of which applies to your watch.

— How We Approach Every Service —

The Method Does Not Change With the Tier

Regardless of which service a watch needs, the intake process is the same: condition photograph, numbered service slip, written assessment, scope confirmation before work begins. A quick battery visit receives the same systematic intake as a complication restoration — only the work that follows differs.

This consistency matters. It means an owner can bring a ฿4,400 battery service and a ฿18,000 restoration to the same counter and trust that both are handled with the same regard for documentation and communication.

The three tiers differ in the depth of intervention required — not in the care or process applied.
