Skeleton Display Caseback Grand Seiko 61GS 6145 6155 6156

This is a skeleton display caseback for Grand Seiko 61 series watches, using a sapphire crystal. It is made in Japan.

The Grand Seiko's unique skeletonized rotor and 10-vibration temple movement can be seen while using the watch, making it a great option for those who appreciate the labor of love engraved on the caseback.

By preserving the original caseback, you can also prevent medalion degradation or peeling.

* This product is a caseback only. The watch body image is for reference only.

Product Information

We have carefully crafted this new model to fit the Seiko style, with a focus on shape. The glass part has been made smaller than the previous model, making it less visible around the 61 movement.

Making the glass part smaller has made the production dimensions more challenging, but it has also improved the appearance.

The material is SUS stainless steel, and this time it is slightly thinner than the original caseback with medalion.

The skeleton part uses a sapphire crystal, and it is attached with a 10-atmosphere compatible adhesive. The caseback is screwed onto the case body smoothly. A new O-ring is also included.
