Jam Ikan today... +6 sec per day... no chronometre but still within COSC specs
i wonder u really time your watch everyday?
is the few second that important to u?
hehehe just to make sure all this COSC stuff or superlative bla bla thing really work or just marketing strategy.
so far im quite satisfied with the result... and sumo is the most accurate watch in my collection... beat all those more expensive one
even his big brother Marinemaster... not that important la, just another way of enjoying my watch... i think
Swiss vs
Japanthe rice bead bracelet is comfortable... but the orange dial, superb.
