An icon, 40 years in the making. Our limited-edition 5657 remaster is supplied with two iconic case bezels. Choose from our tank-like square 5600 dating back to 1987, or the round 5700 case first released 22 years ago. Adorned with milestone watch releases on the strap, together with 40th star details found on the button & hardware. Basic performance is also updated to now feature super illuminator and five-year battery life. A well-rounded square celebration of shock-proof clout.
