When pebble announced the Pebble Core, I thought I'd finally found the answer to my problem: complete a race—having been completely disconnected—while still have the option to connect afterwards as a means of coordination.
When that product was killed off with the sale of Pebble to Fitbit, I was back to hoping someone would fill that niche. This watch now makes that viable. Yes, it's an expensive price to pay (particularly as compared to the Core) but you only have to stand around windy, 20℉ weather in running shorts for an hour once before the price becomes of less consequence.
