Baby-G Frogman BGW-100 Series

We recently covered Baby-G watches with solar and Multi-Band 6 but here is a Frogman that is perhaps the holy grail of Baby-G watches. The Baby-G Frogman BGW-100 Series is no longer in production but it can often be found on eBay in good condition. But is this Baby-G Frogman as full featured and a serious scuba diving watch like the G-Shock Frogman? All signs point to yes. The Baby-G Frogman is ISO standard 200 meter water resistant and features a screw back case just like its big brother.

The BGW-100 takes its design cues from the early G-Shock DW-9900 in a smaller form factor. The BGW-100 started its life as the Japan-made BGW-101 Seaman around 1997 and became the BGW-100 Frogman with a production run until around 2004.

As you can see the Baby-G Frogman is a serious diving watch, just like the G-Shock Frogman. As an older model it lacks Tough Solar power, but it is still an attractive option for women, children, or men with smaller wrists. Surprisingly, these rare Baby-G Frogman usually aren’t that expensive when they pop up on Ebay, with the exception of the BGW-101. Ebay currently has two BGW-100 watches available, a jelly red one in good condition for $250 and a black one in fair condition for $199.
