Caterpillar has long been known for making sturdy machinery, and the company has applied this know-how to the world of mobiles in the past few years.
Samsung has been at this game a little while too, and the first Galaxy to get the toughened treatment was the S4 Active in 2013.
Cat S60: 147.9x73.4x12.7mm, 225g
Galaxy S7 Active: 148.8x75x9.9mm, 185g
You wouldn't mistake the S7 Active for one of Samsung's Galaxy handsets. It's not an ugly phone, but it's a far cry from the S7's sublime curves and beautiful craftsmanship.
Unlike the similarly ruggedised Cat S60, the S7 Active is wholly ensconced in rubber. The Cat S60 looks like it means business, and the stainless steel and carbon fibre mix imbue it with a rugged charm.
Both phones' thick protective shells come with military grading (on top of IP68 certification) and will guard against extremes of temperature, rain, sand, salt, dust, solar radiation, vibration and shock.
It should be noted that the Active was recently blasted in the press after failing two underwater tests. Samsung has since identified manufacturing problems that compromised the phone's water resistance.
The Cat S60, on the other hand, is able to survive at a depth of five metres for up to 60 minutes.
Both handsets are almost identical in terms of dimensions, but the Cat S60 is considerably thicker and heavier.
Winner: Cat S60
Cat S60: 4.7in 1,080x720 resolution with 312ppi, Gorilla Glass 4
Galaxy S7 Active: 5.1in 2,560x1,440 resolution with 576ppi, Gorilla Glass 4, Shatter Resistant
Both handsets come with Gorilla Glass 4, which helps in the event of drops, but the Active adds an extra level of protection to minimise cracking. Instead of the screen shattering outright, the Active will isolate any cracks and leave the rest of the display untouched.
The Active uses a Super AMOLED display so you can expect inky blacks, popping colours and bucket loads of vibrancy.
In the opposite camp, the S60's screen really lets it down. The 4.7in display is only 720p and it really shows when placed alongside a device with QHD numbers. The muted colour palette doesn't help either.
Winner: Galaxy S7 Active
