1. Watch Repair

The First wristwatch was made for Countess Koscowicz by world renown watchmaker Patek Philippe in 1868.

We are quite sure the first watch repair was done early in 1869. Seriously mechanical watches are some of the most complexed mechanisms know to man and do require periodic upkeep. Today's complicated movements can have more than 200 moving parts.

At Thousand Island Diamond Center we can provide service on virtually every type of time piece.

Many simple services – Batteries and bracelet resizing can be completed in the house often in just a few minutes.

For more complexed repairs – overhauls on mechanical watches or batteries on Swiss watches or specialized water resistant watches we have off-site services that can accommodate virtually any brands.

This will serve as a replacement value for your insurance carrier and lets you know the current market value for your fine jewelry. If the item was not purchased at Thousand Island Diamond Center we can still provide this service for you at a nominal charge depending on the complexity of the evaluation.

Fair market value – often clients inherit jewelry and they simply want to verify authenticity and have a rough idea of what their items may be worth. This is an informal consultation that we are happy to do free of charge. If you are interested in selling those items we are happy to make you an offer depending on our need for the items and the component value.
