Roll up, one and all, March Mania has reached its second roundAt this stage, our eight competing writers get a rest. Rob and Dave will present our weary warriors remaining four watches over the next four days, with each post featuring the winners of two first-round votes.Here come the last four standing from Gerard and from RJs groups. The writers arent going head-to-head just yet, so the seedings attached to each watch stay put from the previous round. By the end of the week, well be down to the final two from each initial group of 12 as we barrel towards the showpiece final. As always, what we need from you is simple: vote for your favorite watch and let us know why in the comments below.

Who did you vote for and why? Whats your prediction for the later rounds? Will the Omega Speedmaster 321 triumph once again Who knows? You decide!Gerards Group:(1) Omega Speedmaster Professional 3570.50 (2006) vs. Sinn 142.St 142.010 (2005) (6)Omega Speedmaster Professional 3570.50Again, similar to the previous round, it is not that surprising that we see the Speedy make it through once more. Taking a landslide victory against the Day-Date with 72% of the voting, Goliath took David to the cleaners. At this rate, we are going to see more Speedmasters in the later rounds than I had perhaps naively expectedIf a Speedmaster is to take the crown, will it be the 3570 though? That said, it still has to get past the Sinn 142 next. While the 3570 is definitely the favorite in this matchup, theres still time for a big upset!Sinn 142.St 142.010 (2005)I was pleasantly surprised to see the Sinn 142 make it this far in the competition. Not because its a bad watch (clearly its quite the opposite!), but because I thought it might have struggled in the earlier rounds to carve out its own niche. That was not to be and it even knocked out the Seiko Darth Tuna in the last round (securing 57% of the votes), cementing it as an underdog contender!? Can it take down the Omega Speedmaster 3570 and continue its march towards glory? Well, only time will tell on that one.March Mania: Second Round Proper Gerard (1) V (6)
