Hi guys, i just installed a mesh bracelet on the Seiko SRP639K (nick named Monster Tuna). It sure looks good on mesh bracelet !

The reason for this post is to recommend and suggest the suitable springbar when installing mesh bracelet or leather strap.
The mesh bracelet has a rather small lug hole with max diameter of 2mm. Most commercial springbar comes either in diameter of 1.5mm or 1.78mm but its pin head are only 0.8mm to 1.0mm. These undersize springbar end pin will damage the Seiko lug holes in the long run.

For leather strap you may get away with it by forcing the Seiko fat springbar into the strap lug and stretch the leather. The SRP639K has drilled thru lug, so its no issue removing these fat springbar. But for mesh bracelet in my opinion, the best option is to use these custom 22mm springbar of correct 1.2mm pin head, body diameter is 2mm (fit nicely into the mesh bracelet). See photos below for better understanding.
