Welcome to this SEA-GULL page.

One of the most popular models from Official SEA-GULL, simple but yet busy enough with day and date gauges and of course the memorizing tourbillon.

The crown is set with a blue sapphire stone

As reviewed by Rich Park and as mentioned in the video, it is very easily to buy from the wrong dealer and can end up with a replica Sea-Gull. Faioki ran to the rescue and gave Rich Park the authentic one.
