My LS has a clock feature on the Tach but I don't think it keeps accurate time. I have set it numerous times and it is usually off next time I think about checking it. As you can tell, I don't use it anyway. I put away all my expensive watches several years ago when I started working in Africa, didn't want someone hacking off my hand for my watch. Instead I buy the $10-15 digital watches from Walmart. The keep excellent time, last a couple of years or more till the band wears out and then I just toss them and buy a new one. I don't worry about scratching them up or damage. I like the ones with a Velcro band but they seem to fray the cuff badly on my shirts so I went back to the plastic buckle type on the last one I have 2 of the Velcro ones that still work fine.
