I just had a quick look at the Epson SF-810B (actually I think the SF-810V – violet) and it’s coming in at GBP127! That’s the priceĀ for a PROPER running watch WITH pretty good optical HR.
That’s Ā£100 below the RRP.
It’s a good watch.
It’s cheaper than a Garmin 225/235.
And if you check my review from last year I suggested then that they need to charge Ā£150 in order to shake up the market. They didn’t do that at the time…
Now there are the likes of the TomTom Runner 2/Spark at the same price point. Much more competitive market for optical.
The current price drop could be a stock clearout ahead ofĀ an expected announcement of ‘something’ from them in March. We’ll see.
