My Bio

I started creating my own Koivukoski timepieces - elegant wrist watches as soon as I graduated from The Finnish School of Watchmaking and I´m currently managing it as a full time job.

Reima Koivukoski is a watchmaker based in Southern Finland in his hometown of Espoo.  After attending the Finnish school watchmaking, he spent time in Austria working for Habring2 in micro machining. He then moved to Germany a few years to work in after sales repair and restoration. Lastly, he returned back to Espoo to start KronowerK where his focus is on watch manufacturing, restoration, servicing, prototyping, and small batch precision manufacturing.

Professional Accolades: Reima received the A. Lange & Sohne watchmaking Excellence Award 2015 for prototyping and assembling.

Additional Haute Horology Training: Practice periods at Kari Voutilainen and Christian Klings. One of the only students to complete an Escapement model at the Finnish School of Watchmaking.

Watchmakers Note

It all starts from design idea - idea of the design that fulfills and exceeds demanding needs in our environment today. A unique combination of the latest technology available, easy to wear, easy to service and last but not least a piece of beauty that serves your eyes for decades. 


Details matters: A good example is blued hands - a watchmakers tradition found in the Swiss mountains.  To find a way to prevent watch hands (which at that time were not water resistant) from corroding under the tough climate conditions, where the watchmakers invented the process of bluing. This expertise is utilized in our atelier in a unique way. Several detailed phases and techniques are required to achieve a final product.

Sustainability: Our products - mechanical wristwatches - are sustainable. This is easy to understand to anyone who imagines the mountains of batteries included in quartz watches that have to be disposed of every year. Mechanical wristwatches, on the other hand, are products for generations, if regularly serviced.

Our watches are reliable, durable and easy to wear - targeted for everyday life and making owners happy - a small luxury to wear day after day.

We provide two(2) years international warranty for all our manufactured products.
