Sulu did raise an eyebrow at that, though it was only briefly. It was a little bit of a mix between classy and tacky, he thought; someone who had one of those was definitely a tourist, but he knew it was probably better than a snowglobe or tee shirt. More... elegant, or something. He didn't really like watches, especially classic analog ones, but hey. ...Did they even have digital ones in Ianto's time?

He nodded. "Yeah? So we're going with the Starfleet watch?" He clearly had no problem with it - his question was more prodding than anything, like he was trying to ask why Ianto was picking that without sounding like he was asking that.
