Implementing separate locked/unlocked faces on js2

Okay.... here's what I have:

const xc=88, yc=88;
var twoPi  = 2*Math.PI;
var Pi     = Math.PI;
var halfPi = Math.PI/2;
//daylight_images
var faceDaylight = require("Storage").read("FaceDaylight.gif");
var hourHandDay = require("Storage").read("HourHandDay.gif");
var minHandDay = require("Storage").read("MinHandDay.gif");
var secHandDay = require("Storage").read("SecHandDay.gif");
//nightglow_images
var faceGlow = require("Storage").read("FaceGlow.gif");
var hourHandGlow = require("Storage").read("HourHandGlow.gif");
var minHandGlow = require("Storage").read("MinHandGlow.gif");
var secHandGlow = require("Storage").read("SecHandGlow.gif");
//
var drawTimeout;

function daylight() {
  var d = new Date();
  var h = d.getHours() % 12 || 12;
  var HoursAngle   = (d.getHours()+(d.getMinutes()/60))/12 * twoPi - Pi;
  var MinutesAngle = (d.getMinutes()/60) * twoPi - Pi;
  var SecondsAngle = (d.getSeconds()/60+d.getMilliseconds()/60000) * twoPi - Pi;
  g.reset();
  g.clear();
  g.drawImage(faceDaylight);
  //DateWindow
  g.setFont("6x8");
  g.setFontAlign(0,0);
  g.setColor(0,0,0);
  g.drawString(d.toISOString().substr(8,2), 138, 88, 0);
  g.drawString(d.toISOString().substr(8,2), 139, 88, 0);
  g.drawImage(hourHandDay,xc,yc,{scale:1,rotate:HoursAngle});
  g.drawImage(minHandDay,xc,yc,{scale:1,rotate:MinutesAngle});
  g.drawImage(secHandDay,xc,yc,{scale:1,rotate:SecondsAngle});
  queueDraw();
}

function nightglow() {
  var d = new Date();
  var h = d.getHours() % 12 || 12;
  var HoursAngle   = (d.getHours()+(d.getMinutes()/60))/12 * twoPi - Pi;
  var MinutesAngle = (d.getMinutes()/60) * twoPi - Pi;
  var SecondsAngle = (d.getSeconds()/60+d.getMilliseconds()/60000) * twoPi - Pi;
  g.reset();
  g.clear();
  g.drawImage(faceGlow);
  g.drawImage(hourHandGlow,xc,yc,{scale:1,rotate:HoursAngle});
  g.drawImage(minHandGlow,xc,yc,{scale:1,rotate:MinutesAngle});
  g.drawImage(secHandGlow,xc,yc,{scale:1,rotate:SecondsAngle});
  queueDraw();
}

function draw(){
  if(Bangle.isLocked()){
    daylight();
    } else {
    nightglow();
    }
}

function queueDraw() {
  if (drawTimeout) clearTimeout(drawTimeout);
  drawTimeout = setTimeout(() => {
    drawTimeout = undefined;
    draw();
  }, 250 - (Date.now() % 250));
}
Bangle.on('lock', on => {
  draw();
});
draw();

Still getting the tiniest delay, though I think it is better than it was.
