An interesting feature of this #seiko #prospex SBDY001 is the inbuilt #magnifying glass. There is a button at 9 o'clock which would extend the glass (seen here). This watch was originally targeted to #scientists. However, it is also good for #campers and #adventurers as you can also make fire when there is a sun. #watchoftheday #watchesofinstagram #watchmania #watchlover #watchfam
