The timber in your clock is Plantation Grown Mahogany which is sourced from ecologically sustainable forests in South East Asia. This industry provides a welcome income for the locals in these regions.
The natural timber clocks feature an oil finish (I want the finish to be IN the timber, not ON the timber). 
This allows the timber to breathe and will require from time to time a freshen up with a good quality furniture wax or oil.
Please keep your Tide Clock away from direct sunlight wherever possible to maintain the quality of your timber.Unfortunately, availability of some components, especially the hands, can be difficult so the clock you buy may look slightly different to those pictured.
Please note that timber is a natural resource and I do not stain the timber in your clock, so natural variations in timber colour and grain will occur.
My wife Christine and I (Peter) create interesting functional pieces for our Gallery and teach unique crafts in our workshops.
I hope you enjoy using your tide clock as much as I enjoyed making it for you.

Regards
Peter
